Divide Fractions & Mixed Numbers w/ Cross Cancelling Terms (Simplify Fractions) - [7-2-14]

In this lesson, you will learn how to divide fractions and mixed numbers. In order to divide fractions, we must first change the division into multiplication, then multiply by the reciprocal of the second fraction. Because of this, all fraction division becomes a multiplication problem. If a mixed number is present, just convert the mixed number into an improper fraction before proceeding. Always simplify the result and use cross cancellation to make the problem simpler prior to carrying out the multiplication step.

I havent seen this stuff since 7th grade, its been over a decade. Watching this made it all come back in a flash. I underestimate my own brain.

great tutorial which will definitely help students to simplify fractions, thanks for the lesson

Welcome!

that helps me a lot..thank you for that, i can now explain it clearly to my daughter

Rarely do I see the division of fractions explained as, simply, numerator divided by numerator, denominator divided by denominator (when such straightforward division is manageable) 1/4 divided by 1/2 = 1/1 over 4/2 = 1/2. "Keep/Change/Flip" as a procedure is most helpful. Sometimes, though, it's an unnecessary extra step

I am terrified of my GED test. I have no brains for math. Great explanation, I got some answers out of this video.

Hey. How's it going. Turns out that I didn't need math to explain our Light Matrix Vortex. Hope you've been working on this. I was serious you should get in on the Institutional math before someone else gets it. Next video is Polorized Crystal Light Propulsion. Should be a jaw dropper.

Nice

So can I not cross cancel before I flip the fraction? say if I had two fractions divided like (2/13) / (1/2)? Could I not cancel both 2's out before I flip the fraction and multiply?

DAMN GOOD 👍

Hey first time on your channel. Do you make videos on jee mains and advanced???

Graphical interpretation easy when dividing a larger fraction by a smaller one. I think it's somewhat involved when dividing a smaller fraction by a larger one.

@@soap3044 well done, thanks.Suppose we have 1/2 pizza and 1/4 pizza i.e 1/2÷1/4=2 that means 2 pieces of 1/4 pizza fits into 1/2 pizza. When 1/4÷1/2=1/2, how many pieces of 1/2 pizza fits into 1/4 pizza ? That's is half. Graphical interpretation is that half of 1/2 pizza fits into 1/4 pizza. Right? Same is it?

@@soap3044 verify with rectangular diagrams. 1.Draw two rectangles of same size one below the other. 2. Divide those rectangles according to fractions and shade the regions. 3. Compare the shaded regions i.e overlapping the shaded regions.

@@soap3044 yes as calculations become complex, it's difficult to understand their meaning. The only way is to follow certain shortcuts or rules.
