If you miss 9 questions, the how many did you get right?
85 - 9 = 76
So now you got 76 out of 85 correct or 76/85...
Now if you just do the fractional division that is described by the fraction you will get the answer. The fraction bar literally means "divided by", so the fraction means...
76 divided by 85 which equals...
.8941
Now to convert to percentage we multiply by 100 (move the decimal 2 places to the right)
.8941 x 100 = 89.41% Round to nearest one percent...
89%
