0.8 is eight tenths. 8/10 = 4/5

0.137 is one hundred thirty seven thousandths. 137/1000

2.45 is 2 and 45 hundredths. 2 and 45/100 = 49/20

 

To turn a fraction into a decimal just put it in a calculator. 2/3 ≈ 0.666667

To turn a fraction into a decimal, simply divide to two numbers. For example 3/4= .75

 

30-28=2

20-20=0

 

_________________________________________________________________________________________________________

 

To turn a decimal into a fraction multiply the number by 10number decimal places this is your denominator.

 

For example

 

.02 = 2/(102) = 2/100

 

Now simplify

 

1/50
