8/8 - 1/8 = 7/8
7/8 = 0.875
Multiply 0.875 by 100 and attach the % sign
0.875 x 100 = 87.5%
The answer is 87.5%
- - - - - - - - - - -s-

(8 - 1)/8 = 7/8. In other words, 7 of 8 problems right.
Since percent is just a fancy form of saying "divided by 100", let's find a fraction, with denominator 100, which is equal to 7/8.
x/100 = 7/8
x = 7 * 100 / 8
x = 700/8 = 87.5
So, the percentage of correct problems is 87.5%.

if you got one wrong, then there would be 7 out of the 8 problems right, which is 7 / 8 or 87.5% correct
