How do you calculate percent on a calculator?

Answer 1

To find a percentage of a given number, multiply the number times the percentage expressed as a decimal : a percent equals 1/100 so 20% of a given number is that number times 0.20 (20/100).

Example :

To find 5% of 50.00, multiply 50.00 x 0.05 = 2.50 *

To find one number as a percent of another number, divide the value of the number by the other number, then multiply the decimal result by 100 and that is the percent (per 100) value.

Examples:

What percent of 52 is 13?

To find the value of 13 compared to 52, divide 13 by 52 = 0.25

Now the percentage is 100 times that or 25 percent.

And 13 is 25 percent of 52

What percent of 50 is 150?

Divide 150 by 50 and the answer is 3, multiply by 100 to yield 300%

150 is 300% of 50

* Some calculators have a percent function (usually marked with a '%' icon). If yours does, just follow the same procedure but you won't have to convert the 'percent number' into a decimal. In the same example above, you would input: 50 x 5 and then % - the calculator will automatically give you the answer (2.50).

Answer 2
