convert 0.12 to fraction

Answer 1

1. count the number of decimal places,
in this case there are 2
divide by 100 -----> 12/100
2. reduce the fraction to lowest terms
12/100 = 3/25

(if 1 decimal place, divide by 10
if 2 decimal places, divide by 100
if 3 decimal places divide by 100
etc
e.g.
.2568
= 2568/10000
= 131/1250

Answer 2

just noticed a typo
should have said:
if 3 decimal places divide by 1000

but you probably figured that out anyway.
