Answer:
64/100
Explanation:
Write down the number as a fraction of one
0.64 = 0.64/1
Then multiply both top and bottom by 10 every number after the decimal point.
As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,
0.64/1 = (0.64 x 100)
_________ = 64/100
(1 x 100)
