- In this movie, I'll explain how to work with fractions.…Which are just ways to show how much of a whole there is.…Just like decimals.…So really easy example of a fraction, 1/2.…So 1/2 is just one half of one.…So the 1 in 1/2 is what we call…the numerator of the fraction,…and the bottom part of the fraction, the 2,…is what we call the denominator of the fraction.…The bar in the fraction is a symbol…that just means to divide.…
Normally when we use fractions,…we're not gonna actually divide the two numbers.…But it'll come in handy later.…So a couple things I wanna show you…how to do with fractions.…The first thing is how to reduce fractions.…So let's say we have the fraction 4/8.…If you suspect you might be able to reduce a fraction,…what you wanna think to yourself is,…"Can I find a number that will divide evenly…"into the top of the fraction…"and into the bottom of the fraction?"…So let's think about it.…For 4/8, 2 could go into 4 and 8,…and even better, to find a bigger number,…4 could go into both 4 and 8.…
So what we'll do is to divide the top by 4,…
