Turn a decimal into a fraction?

Answer 1

if you have a decimal number, say .168, you can multiply by ten until it is a whole number:

.168*10 = 1.68

1.68*10 = 16.8

16.8*10 = 168

then, to make it equal, you divide it by 10 to the power of the number of times you had to multiply by ten, in this case, 3 so:

.168 = 168/1000

it's always good to simplify, so:

.168 = 84/500

=42/250

=21/125 which is in simplest terms, so:

.168 = 21/125
