Looking for a guide on how to tell whether two fractions are rationally equivalent to one another? From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test). With this installment from Internet pedagogical superstar Salman Khan's series of free math tutorials, you'll...

In this video the instructor teaches about equivalent fractions. When given a problem to determine if two fractions are equivalent fractions the first thing to do is write them in the lowest terms. A fraction is said to be in the lowest terms if the greatest common divisor of both numerator and denominator is one. So cancel the common factors in the numerator and the denominator till you arrive at the lowest form and finally compare them to determine if they are equivalent. An equivalent frac...

In this tutorial you will learn how to determine and work with equivalent fractions. If you do not know what an equivalent fraction is or how to find them, this is the video for you.

In this video the tutor explains about the concept of Equivalent Fractions and how to find them. She states that equivalent fractions are fractions with same value. She explains this with an example saying that a fraction can have many forms in their unreduced states and all these fractions will have the same value which can be obtained by reducing them. She shows that we can make an equivalent fraction of any fraction by multiplying the numerator and the denominator by the same number and go...

In this video, we learn how to understand and determine equivalent fractions. If you have an equation with an equivalent fraction, you will first multiply the first numerator by the second denominator. Then, you will divide this answer by the denominator of the first fraction. After you do this, it will give you the correct answer. You can also do the reverse multiplication for this to check your answer and make sure you are correct. You can get an answer no matter what the numbers in the equ...

In this tutorial, we learn how to write equivalent fractions. If you have a negative in front of the fraction, it's the same as writing the negative on the numerator or the denominator. If we would have a negative on the top and on the bottom, this would cancel both out to create a positive, which wouldn't be right. To write the fractions, simplify it. If it's already simplified, you will need to multiply the fraction. After you do this, you will finish the equation and have it written out in...

A representative from Math Problem Generator explains in this video that converting a simple fraction from its current state to a higher equivalent can be very simple. He explains the process neatly and provides a great example. To convert a fraction, you must multiply the numerator and the denominator by the exact same number. The example he shows is captured from the screen of a computer and is written out in some sort of a painting program. The example shows that four-ninths equals eight-e...

I remember these from the election, but never saw a game related one till now.

It’s called Urophagia—the art of consuming urine. There could be any number of reasons for having the desire to drink your own urine (or somebody else’s). There’s the so-called term “urine therapy,” which uses human urine as an alternative medicine. In urine therapy, or uropathy, it’s used therapeutically for various health, healing, and cosmetic purposes. There’s also those people who drink urine as sexual stimulation, where they want to share every part of each other. And then there’s the o...

Hydrazine sulfate has many uses, but most notably, it's been used under the trade name of Sehydrin, a treatment for anorexia, cachexia and some even think cancer. But for we DIY chemists, it's useful for something entirely different— as a substitute for the more dangerous pure liquid hydrazine in chemical reactions. NurdRage shows you how to make it via some hypochlorite and the Ketazine process.

Okay, so you don't necessarily have to make ammonium nitrate to have ammonium nitrate — ammonium nitrate can simply be obtained from fertilizers and instant cold packs. Making homemade NH4NO3 can be much more expensive then buying it, but this video is not meant to be a viable route, it's an exploration of science and chemistry.

A rocket stove is a "rocket" combustion approach to preparing meals, which provides high combustion efficiency and efficient heat transfer to the cooking pot. Research suggests (through practical experience) that by using a rocket stove, you could save at least 50% of fuelwood, which is a significant savings for anyone's financial situation.

Learning a scale is a lot like learning an alphabet. So like an alphabet, once you've learned a scale, it's important to start learning how to improvise on that scale in your guitar playing. This step is like learning letter combinations (th for example) and is an important step before learning licks(the equivalent of words).

WPA-secured wireless networks, or WiFI Protected Access, is a form of internet security that secures your wireless LAN from being accessed by unauthorized users. Safer than WEP, or wireless equivalent privacy, WPA still has weaknesses that are prone to cracking - IF, that is, you know what you're doing.

If you're still drinking tea from water infused with a dinky little tea bag then you're not really drinking tea at all. In fact, drinking tea from a tea bag you get at Ralph's is equivalent to eating a burger and fries at a fast food joint and thinking it's real food.

In this video, we learn how to use compound tenses with "haber" and "estar" in Spanish. "I am speaking" would translate into "You estoy hablando". If you are talking about a girl eating, you would say "Ella esta comiendo". To say "they were writing letters", you would say "Ellos estaban escribiendo cartas". You will see the form of the verb changing in each of the sentences. You will also see the gender of the verb changing in each of the sentences, depending on who is being talked about. The...

An enharmonic equivalent doesn't sound like fun, but in fact the term is fancy jargon for a rather simple concept: it is the duplicate of a note, key signature, or interval that is spelled differently. So two notes are enharmonic if they have the same pitch but are named differently. At least, this is the basis for enharmonic equivalents.

We love this hair tutorial because it teaches you how to create the equivalent of a cinnamon bun on the side of your head. A Dutch braid is basically a braid that you swirl around and around itself in order to form a circular shape. While doing this on both sides of your head would be a little much (we're not going for Princess Leia here), opting for just a single Dutch braid on one side.

If you haven't tried popovers then you haven't experienced an experience that's equivalent to having fireworks lighting up in your mouth. With the fluffiest crust ever that resembles a muffin top and a hollow center just big enough to fill with custard or chocolate, it combines doughy goodness with creamy sweetness in the center.

In this video the tutor shows how to compare exponential expressions and judge if they are equivalent. He shows how to do this using examples to simply exponential expressions. Now after simplifying the numerator and denominator separately he reduces the fraction to arrive at a simple value. Now using this simple values we can compare them and judge if both their values are equivalent. This video gives a good introduction on how to simplify the exponential expression and how to compare them a...

Fractions are numbers of the form a/b, where a and b are integers. Fractions are also called as ratios. Fractions are further divided into proper fractions and improper fractions. Proper fractions are those where the numerator is less than the denominator and improper fractions are those where the numerator is greater than the denominator. As fractions are ratios a fraction can have many equivalent forms. Multiplying the numerator and denominator of a fraction with a same number gives a fract...

This video from Yay Math! is a geometry lesson on how to complete a proof involving segments. He draws a line segment with four points labeled A, B, C and D. The problem is as follows: Given: AC is equivalent to BD. Prove that AB is equivalent to CD. The first statement of proof is the given. Next, you need to define the congruent segments and state that they're equal in measurement. Next, break down the segments: AC=AB+BC, and BD=BC+CD. This is called segment addition postulate. The end of t...

This how-to video explains about how to add fractions with uncommon denominators. To add fractions with uncommon denominators three steps are involved:
