# Question: 81 is 27 percent of what number?

## Step by step solution for calculating 81 is 27 percent of what number

We already have our first value 81 and the second value 27. 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 81 = 27% × Y

STEP 2 81 = 27/100× Y

Multiplying both sides by 100 and dividing both sides of the equation by 27 we will arrive at:

STEP 3 Y = 81 × 100/27

STEP 4 Y = 81 × 100 ÷ 27

STEP 5 Y = 300

Finally, we have found the value of Y which is 300 and that is our answer. You can easily calculate 81 is 27 percent of what number by using any regular calculator, simply enter 81 × 100 ÷ 27 and you will get your answer which is 300 Here is a Percentage Calculator to solve similar calculations such as 81 is 27 percent of what number.

## Sample questions, answers, and how to

Question: Your friend has a bag of marbles, and he tells you that 27 percent of the marbles are red. If there are 81 red marbles. How many marbles does he have altogether?

How To: In this problem, we know that the Percent is 27, and we are also told that the Part of the marbles is red, so we know that the Part is 81.

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 81.

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

81 × 100 = 8100

In step two, we take that 8100 and divide it by the "Percent", which we are told is 27.

So, 8100 divided by 27 = 300

And that means that the total number of marbles is 300.

Question: A high school marching band has 81 flute players, If 27 percent of the band members play the flute, then how many members are in the band?

Answer: There are 300 members in the band.

How To: The smaller "Part" in this problem is 81 since there are 81 flute players and we are told that they make up 27 percent of the band, so the "Percent" is 27.

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.

81 × 100 = 8100

For step two, we divide that 8100 by the "Percent", which is 27.

8100 divided by 27 equals 300

That means that the total number of band members is 300.

## Another step by step method

Step 1: Let's assume the unknown value is Y

Step 2: First writing it as: 100% / Y = 27% / 81

Step 3: Drop the percentage marks to simplify your calculations: 100 / Y = 27 / 81

Step 4: Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 27 / 81 ) Y

Step 5: Simplifying the right side, we get: 100 = 27 Y

Step 6: Dividing both sides of the equation by 27, we will arrive at 300 = Y

This leaves us with our final answer: 81 is 27 percent of 300
