# Question: 10 is 15 percent of what number

## Step by step solution for calculating 10 is 15 percent of what number

We already have our first value 10 and the 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 10 = 15% × Y

STEP 2 10 = 15/100× Y

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

STEP 3 Y = 10 × 100/15

STEP 4 Y = 10 × 100 ÷ 15

STEP 5 Y = 66.667

Finally, we have found the value of Y which is 66.667 and that is our answer.

You can easily calculate 10 is 15 percent of what number by using any regular calculator, simply enter 10 × 100 ÷ 15 and you will get your answer which is 66.667

## Sample questions, answers, and how to

Question: Your friend has a bag of marbles, and he tells you that 15 percent of the marbles are red. If there are 10 red marbles. How many marbles does he have altogether?

How To: In this problem, we know that the Percent is 15, and we are also told that the Part of the marbles is red, so we know that the Part is 10.

So, that means that it must be the Total that's missing. Here is the way to figure out what the Total is:

Part/Total = Percent/100

By using a simple algebra we can re-arrange our Percent equation like this:

Part × 100/Percent = Total

If we take the "Part" and multiply it by 100, and then we divide that by the "Percent", we will get the "Total".

Let's try it out on our problem about the marbles, that's very simple and it's just two steps! We know that the "Part" (red marbles) is 10.

So step one is to just multiply that Part by 100.

10 × 100 = 1000

In step two, we take that 1000 and divide it by the "Percent", which we are told is 15.

So, 1000 divided by 15 = 66.667

And that means that the total number of marbles is 66.667.

Question: A high school marching band has 10 flute players, If 15 percent of the band members play the flute, then how many members are in the band?

Answer: There are 66.667 members in the band.

How To: The smaller "Part" in this problem is 10 since there are 10 flute players and we are told that they make up 15 percent of the band, so the "Percent" is 15.

Again, it's the "Total" that's missing here, and to find it, we just need to follow our 2 step procedure as the previous problem.

For step one, we multiply the "Part" by 100.

10 × 100 = 1000

For step two, we divide that 1000 by the "Percent", which is 15.

1000 divided by 15 equals 66.667

That means that the total number of band members is 66.667.

## Have time and want to learn the calculation?

Let's assume the unknown value is Y

First writing it as: 100% / Y = 15% / 10

Drop the percentage marks to simplify your calculations: 100 / Y = 15 / 10

Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 15 / 10 ) Y

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

Dividing both sides of the equation by 15, we will arrive at 66.667 = Y

This leaves us with our final answer: 10 is 15 percent of 66.667
