Thank you We sneak in and here's your shmoop too

00:05

sure brought to you by reduced fractions Hey the best

00:08

things can come in Reduce packages alright Produced the fraction

00:12

fifty for ninety nine's chair and here the potential answers

00:21

Okay so this question simply wants us to take the

00:24

fraction fifty for over ninety nine and reduce it as

00:28

much as possible Like the biggest loser we could spend

00:31

a bunch time trying to figure out what the largest

00:33

number is that we can divide out of both the

00:36

numerator and denominator But we're actually fans the shortcuts around

00:39

here You should see how little time and takes us

00:41

to finish a marathon Yeah any way we can start

00:44

by dividing out a very small number that we feel

00:47

confident divides into both numbers just to make the thing

00:50

a bit more manageable Well it certainly looks like three

00:53

is a factor of ninety nine which indeed it is

00:55

So does it go evenly into fifty for you Bet

00:58

if we divide top and bottom by three we get

01:01

eighteen over thirty three Oh both Numbers are still divisible

01:05

by 3 so let's do it again and we get

01:09

six over eleven which is answered choice See And we're

01:12

done But there's extra credit here If you had recognized

01:16

right off the bat that both fifty four and ninety

01:20

nine are divisible by nine Well then more power to

01:23

you and there's a little trick here five plus four

01:27

right there equals nine which is visible by three and

01:30

nine plus nine is eighteen which is visible by three

01:34

and well that's Just another trick for you So you

01:36

would have saved yourself an extra couple of seconds if

01:39

you'd followed our path there But well we hope you 00:01:41.696 --> [endTime] made the most of it
