1-Minute Math: Multiplying Fractions. Learn 2 ways to multiply fractions in less time than it takes to order a pizza!

Multiplying two fractions together can be pretty straightforward if we have

a/b x c/d we just multiply straight across and have a times C/B x D

For example 3 over 4 times 1 over 5 we'll just end up being 3 over 20

sometimes though the end result won't always be in simplest form let's take a

look at another example 6 over 7 times 3 over 4 if we multiply straight across

would be 18 over 28 these two values have a common factor though we can

factor 18 into 9 times 2 and 28 into 14 times 2 reduce and have our final answer

of 9 over 14 another way to approach this is to simplify first notice here

that 6 and 4 have a common factor of 2 so if we factor first we can reduce the

twos out right away multiply across and end up with 9 over 14 as well both ways

will always work but simplifying first can avoid some large values that are

difficult to deal with.
