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
