You have to write an equation for this. When you do percents, you always have to convert them to decimals. (Therefore, 80% is .80 as a decimal)
.80x = 8
Divide both sides of the equation by .8 and you'll get
x = 10

When changing a percent to a decimal why do you have to move the decimal 2 places?
A percent is simply a decimal number written as a number over 100. For example, .8 = eight tenths = 8/10 = 80/100 = 80 percent.
