The fastest step by step guide for calculating what is 20 percent of 390

We already have our first value 20 and the second value 390. 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 = 20/100

STEP 2 Y = 20/100 × 390

STEP 3 Y = 20 ÷ 100 × 390

STEP 4 Y = 78

Finally, we have found the value of Y which is 78 and that is our answer.

Let's solve the equation for Y by first rewriting it as: 100% / 390 = 20% / Y

Drop the percentage marks to simplify your calculations: 100 / 390 = 20 / Y

Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 390 ) = 20

To isolate Y, multiply both sides by 390 / 100, we will have: Y = 20 ( 390 / 100 )

Computing the right side, we get: Y = 78

This leaves us with our final answer: 20% of 390 is 78
