In this video we learn how to reduce a fraction to its lowest terms by canceling common factors from the numerator and denominator. We can ensure that we've reduced the fraction as much as possible by factoring both the numerator and denominator to a product of primes, and then canceling the common prime factors. This is especially helpful when we have to multiply fractions together that have large numbers in their numerators and/or denominators. Instead of multiplying the large numbers and then trying to reduce huge numbers, we can instead cancel factors from the smaller numbers and do the multiplication with whatever remains.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
