How to write 7/8 as a percent

First, you'd have to turn the fraction into a decimal.You would divide the numerator by the denominator.  7/8=0.875
Now, you turn the decimal to a percent.
You move the decimal point two places to the right.
087.5
87.5% would be your answer.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
