 You
need to divide the numerator(top
number) by the denominator(bottom
number)
 Example
 Think
1
8
Numerator
8 1.
Denominator
“top dog in the house- bottom out”
0.1 2 5
8 1.0 0 0
8
20
16
40
40
So the
decimal
is 0.125!
 Think
Dr P for Doctor Pepper!
D is for decimal
 We
r is a reference P is for percent
point
either multiply or divide by 100, so the
shortcut is to move the decimal 2 places
either left or right!
 Let’s
change the decimal 0.125 into a %!
D
r
P
.
0 .1 2 5
So our new percent is
12.5%
We are going
from decimal
to percent so
we go 2 to the
right!
D r .P
This time we start at
the P for percent!
We are going 2
places left.
2 1.%
So our decimal
is 0.21
If you don’t
see the
decimal it is
after the
ones digit!
Percent means “out of 100” so just put your
percent on top of your fraction and put 100 as your
denominator!
85 %
÷5
85 17

100 20
÷5
85
100
If you can
simplify the
fraction, go
ahead and do
so!
Both 85 and
100 are
divisible by 5!
 Read
it
 Write it
 Reduce it
Now write
what you just
said!
0.26

100
Read the decimal. It
is twenty-six
hundredths.
Go ahead
and simplify
if you can.
Our fraction is:
