How do you turn 0.78 into a fraction?

Answer 1

The numerator of the fraction is the decimal number WITHOUT the decimal point. The denominator of the fraction is 1 followed by the same number of 0s as there were digits after the decimal point in the original number. Then simplify this fraction by dividing both numerator and denominator by any common fractions - they will be 2 (or 2*2 or 2*2*2 etc) or 5 (or 5*5 or 5*5*5 etc).

Here, number of digits after the decimal point is 2. So denominator = 100. So the fraction is 78/100.

Simplifying, 78/100 = 39/50.
