The fastest step by step guide for calculating what is 40 percent of 31

We already have our first value 40 and the second value 31. 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 = 40/100

STEP 2 Y = 40/100 × 31

STEP 3 Y = 40 ÷ 100 × 31

STEP 4 Y = 12.4

Finally, we have found the value of Y which is 12.4 and that is our answer.

If you want to use a calculator to know what is 40 percent of 31, simply enter 40 ÷ 100 × 31 and you will get your answer which is 12.4

Let's solve the equation for Y by first rewriting it as: 100% / 31 = 40% / Y

Drop the percentage marks to simplify your calculations: 100 / 31 = 40 / Y

Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 31 ) = 40

To isolate Y, multiply both sides by 31 / 100, we will have: Y = 40 ( 31 / 100 )

Computing the right side, we get: Y = 12.4

This leaves us with our final answer: 40% of 31 is 12.4
