Multiplying fractions is as easy as pie... and significantly easier than pi.

their own numerators and denominators then we multiply the two numerators

together giving us the product's numerator and we multiply the two denominators [Dino and Coop looking at a blackboard]

together giving us the product's denominator if there are any common

factors we simplify them out and that's it. No seriously, that's it. We

know it's almost too easy like going fishing and having the fish just jump

into your boat, but hey sometimes you get lucky. Still not convinced that easy? Well,

A - how dare you call us liars and B - let's check out an example. Let's say we [Guy in Shmoop shirt looking offended]

want to find the product of three quarters and five sevenths. First we

multiply our numerators on top we've got 3 times 5 which gives us 15 next we

multiply those denominators down below we've got 4 times 7 which is 28 and

since fifteen and twenty eight share no common factors we're done. Easy as pie, or

fifteen twenty eighths of a pie good luck measuring out that slice. This [Man dances in front of pies]

method even works if we want to multiply fractions and whole numbers. Say if you want to

find the product of 5 sixths times 9 we just transform 9 into a fraction by placing

it over 1 then same ol same ol 5 times 9 is 45 and 6 times 1 is 6. 45 and 6 do

have a common factor of 3, so once we simplify that out of the numerator and [Dino and Coop looking at a blackboard]

the denominator we're left with 15 halves and we're done. Math that doesn't

require us to work on it until dawn? Sign us up! Well probably wear sweats or [Student sleeping on a couch]
