Question: 78 is 15 percent of what number

Answer: 78 is 15 percent of 520

Solution for calculating 78 is 15 percent of what number

We already have our first value 78 and second value 15. 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 78 = 15% × Y

STEP 2 78 = 15/100× Y

Multiplying both sides by 100 and dividing both sides of the equation by 15 we will arrive at:

STEP 3 Y = 78 × 100/15

STEP 4 Y = 78 × 100 ÷ 15

STEP 5 Y = 520

Finally, we have found the value of Y which is 520 and that is our answer.

You can easily calculate a similar type of calculation by using any regular calculator, simply enter 78 × 100 ÷ 15 and you will get your answer which is 520

Have time and want to learn the calculation?

Let's assume the unknown value is Y

First writing it as: 100% / Y = 15% / 78

Drop the percentage marks to simplify your calculations: 100 / Y = 15 / 78

Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 15 / 78 ) Y

Simplifying the right side, we get: 100 = 15 Y

Dividing both sides of the equation by 15, we will arrive at 520 = Y

This leaves us with our final answer: 78 is 15 percent of 520
