how do you write 70% percent out of 400 as a decimal?

Answer 1

Percent is a quantity over 100.

70% is equal to 70/100.

Multiply this by your whole which is 400.

70 / 100 * 400 = 28,000 / 100 = 280

Your final answer is 280.

Answer 2

Per cents are based on a system of 100. For example, 70% would be 70/100.

Decimals are also based on a system of 100. 0.1 is 1/10, 0.01 is 1/100, 0.001 is 1/1000.

Therefore, 70% would be 70/100 or 0.70.

The term "out of" means "multiply".
