Best Answer

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

What percent of 80 is 10?

To find 10 percent of a number, multiply the number by 0.1. In this instance, 0.1 x 80 = 8. Therefore, 10 percent of 80 is equal to 8.First let's consider the definition: "per cent (per 100)". If you have 1 "per cent" it means for every 100 you would get 1.Now, to calculate percent, drop the percentage sign and divide by 100. That is,10% = 10/100 = 0.1Now multiply 80 by this to get the answer, 8.

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. Notice, to get from the original .8 to our answer in percent, we just moved the decimal two places to the right (.8 -> 8. -> 80.) So, to change a percent to a decimal, you just reverse the process, so you move the decimal two places to the left. 80 percent -> 8 -> .8 (as a decimal) or 65 percent -> 6.5 -> .65 (as a decimal)
