okay We won't make this political You can start to

00:20

develop a bit of a headache when you see a

00:22

problem like this So many digits So many zeros but

00:26

there's actually a really easy trick that makes these problems

00:28

that total breeze And i'll save you a trip to

00:30

the medicine cabinet for a dose of excedrin Let's Suppose

00:33

we got this problem Oh five two divided by point

00:37

one three Where do we even begin Well it's going

00:40

to be a heck of a lot easier if we

00:42

divided by a whole number So let's do that We

00:44

start by moving the decimal place in each number over

00:47

as many spaces Is it takes to make a point

00:49

O one three are divisor ah hole number Are we

00:52

allowed to do that Well why isn't anyone blowing a

00:55

whistle here Group in mind that whenever we divide one

00:57

number by another were basically creating a fraction point Oh

01:01

five two divided by point one three is the same

01:03

asked point Oh five two over point one three So

01:08

if we multiply both top and bottom of the fraction

01:10

by a thousand we get point five two divided by

01:13

thirteen the exact same value and much easier to work

01:17

with right thousand over a thousand is one Don't forget

01:20

that from there we just divide like we would any

01:22

long division problem We move the decimal place directly upward

01:26

and wind up with point oh four which is our

01:28

answer and that's Why one decimal being divided by another

01:31

decimal isn't so bad Oh if you don't like the 00:01:34.754 --> [endTime] ruling well you people can appeal
