What is 0.728 as a fraction?

Answer 1

.728 = 728/1000 (the last digit is in the Thousands place so it is the whole number over one thousand)

They are both divisible by 2 so:

728 / 2 = 364

and

1000 / 2 = 500

728/1000 = 364/500

That is also divisible by 2 so:

364 / 2 = 182

and

500 / 2 = 250

That is also divisible by 2 so:

182 / 2 = 91

and

250 / 2 = 125

728/1000 = 364/500 = 182/250 = 91/125

91/125 is fully simplified and is your answer.
