Answer: 87.5%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 7/8 as a percent, we need to find a fraction that is equivalent to 7/8 that has a 100 in the denominator. We can do this by setting up a proportion.

Now, we can use cross products to find the missing value.
700 = 8n
÷8 ÷8 ← divide both sides of the equation by 8
87.5 = n
Therefore, 7/8 is equal to 87.5/100 or 87.5%.
