Question: 20 is 80 percent of what number

Answer: 20 is 80 percent of 25

Solution for calculating 20 is 80 percent of what number

We already have our first value 20 and second value 80. 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 20 = 80% × Y

STEP 2 20 = 80/100× Y

Multiplying both sides by 100 and dividing both sides of the equation by 80 we will arrive at:

STEP 3 Y = 20 × 100/80

STEP 4 Y = 20 × 100 ÷ 80

STEP 5 Y = 25

Finally, we have found the value of Y which is 25 and that is our answer.

You can easily calculate a similar type of calculation by using any regular calculator, simply enter 20 × 100 ÷ 80 and you will get your answer which is 25

Have time and want to learn the calculation?

Let's assume the unknown value is Y

First writing it as: 100% / Y = 80% / 20

Drop the percentage marks to simplify your calculations: 100 / Y = 80 / 20

Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 80 / 20 ) Y

Simplifying the right side, we get: 100 = 80 Y

Dividing both sides of the equation by 80, we will arrive at 25 = Y

This leaves us with our final answer: 20 is 80 percent of 25
