Convert 0.83 into a fraction.

0.83 * 100 = 83, so 0.83 = 83/100.

But in case you meant the slightly more interesting repeating decimal, 0.8333...:

Let x denote this number. Then

10x = 8.333...

100x = 83.333...

==>  100x - 10x = 83.333... - 8.333...

==>  90x = 83 - 8 = 75

==>  x = 75/90 = 5/6

your answer would be 12

24
