A boy was asked to multiply a number by 7/8

instead he divided the number by 7/8 and got the

result 15 more than the correct result The number is? ​

Answer 1

So first you would do 15 x 7/8 which would get you 13.12500 but round it and you would get 13.125 as the original number. If you were trying to get the number it first asked you would do 15 x 13.125 = 196.87500, round that and you would get 196.875.
