Dividing by 100 is the same as multiplying by 1/100 or 0.01, because when you divide by a fraction, in this case 100/1, you actually multiply by the reciprocal, which would be 1/100. For example 4/100 = 4 x 1/100 = 4/100 = 1/25 = 0.04.
You can also just move the decimal two place values to the left to divide by 100. For example, 4/100 = 4. /100 = 0.04 = 1/25
