Answer: 10 percent of 400 is 40

The fastest step by step guide for calculating what is 10 percent of 400

We already have our first value 10 and the second value 400. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1 Y = 10/100

STEP 2 Y = 10/100 × 400

STEP 3 Y = 10 ÷ 100 × 400

STEP 4 Y = 40

Finally, we have found the value of Y which is 40 and that is our answer.

If you want to use a calculator to know what is 10 percent of 400, simply enter 10 ÷ 100 × 400 and you will get your answer which is 40

Have time and want to learn the details?

Let's solve the equation for Y by first rewriting it as: 100% / 400 = 10% / Y

Drop the percentage marks to simplify your calculations: 100 / 400 = 10 / Y

Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 400 ) = 10

To isolate Y, multiply both sides by 400 / 100, we will have: Y = 10 ( 400 / 100 )

Computing the right side, we get: Y = 40

This leaves us with our final answer: 10% of 400 is 40
