     3 x 4 = 12
   12 x 4 = 48
   48 x 4 = 192
 192 x 4 = 768
 768 x 4 = 3072

3 + 12 + 48 + 192 + 768 + 3072 +

Percent means parts out of 100 so one way to do it is to divide the fraction exg
3/4=0.75/1
we want x/100 so multiply both top and bottom by 100
75/100=75%

so just divide the fraction then mulitply by 100
or if possible, convert the bottom number to 100
