well when your finding a percent of any number its pretty simple.

Here is the equation for this problem.

0.05*90=5% of \$90

do the math, 90*.05=4.5

When finding a percent of a number, convert the percent into a decimal and multiply it by the whole number.

Examples

10% of 50 = 0.10*50

7% of 20 = 0.07*20

also remember, to convert a fraction to a decimal;

If it is a one digit number, it will be in this form. 0.0#

If it is a two digit number, it will be in this form. 0.#

If it is 100%, it will be 1.0

If it is past 100%, such as 280%, it will look like this. 2.80
