## Step by action solution because that calculating 12 is 15 percent that what number

We currently have our first value 12 and the second value 15. Let"s i think the unknown value is Y i beg your pardon answer us will find out.

You are watching: 12 is 15% of what number

As we have actually all the forced values us need, currently we have the right to put lock in a basic mathematical formula as below:

STEP 112 = 15% × Y

STEP 212 = 15/100× Y

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

STEP 3Y = 12 × 100/15

STEP 4Y = 12 × 100 ÷ 15

STEP 5Y = 80

Finally, us have found the worth of Y which is 80 and that is ours answer.

You can quickly calculate 12 is 15 percent of what number through using any regular calculator, simply get in 12 × 100 ÷ 15 and you will obtain your answer i beg your pardon is 80

Here is a percent Calculator to solve comparable calculations such together 12 is 15 percent the what number. You can solve this form of calculation with your values by beginning them into the calculator"s fields, and also click "Calculate" to obtain the result and explanation.

Question: your friend has a bag that marbles, and also he tells you the 15 percent the the marbles are red. If there space 12 red marbles. How plenty of marbles walk he have actually altogether?

How To: In this problem, we understand that the Percent is 15, and we are also told the the part of the marbles is red, for this reason we understand that the component is 12.

So, that means that it have to be the full that"s missing. Right here is the method to number out what the full is:

Part/Total = Percent/100

By using a simple algebra we have the right to re-arrange ours Percent equation like this:

Part × 100/Percent = Total

If us take the "Part" and also multiply the by 100, and also then we division that by the "Percent", us will gain the "Total".

Let"s shot it out on ours problem around the marbles, that"s very simple and it"s simply two steps! We know that the "Part" (red marbles) is 12.

So step one is to simply multiply that part by 100.

12 × 100 = 1200

In action two, us take the 1200 and also divide it by the "Percent", which we room told is 15.

So, 1200 divided by 15 = 80

And that way that the total number of marbles is 80.

Question: A high school marching band has 12 flute players, If 15 percent that the band members play the flute, then how many members space in the band?

Answer: There room 80 members in the band.

How To: The smaller sized "Part" in this difficulty is 12 because there room 12 flute players and we are told that they consist of 15 percent the the band, therefore the "Percent" is 15.

Again, it"s the "Total" that"s absent here, and also to uncover it, we just need to monitor our 2 action procedure as the previous problem.

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

12 × 100 = 1200

For step two, we division that 1200 by the "Percent", i m sorry is 15.

1200 separated by 15 equals 80

That means that the total number of band members is 80.

## Another action by action method

Step 1: Let"s i think the unknown value is Y

Step 2: very first writing the as: 100% / Y = 15% / 12

Step 3: fall the portion marks to leveling your calculations: 100 / Y = 15 / 12

Step 4: main point both political parties by Y to move Y on the appropriate side of the equation: 100 = ( 15 / 12 ) Y

Step 5: simplifying the right side, we get: 100 = 15 Y

Step 6: dividing both sides of the equation by 15, we will certainly arrive at 80 = Y

This leaves us with our final answer: 12 is 15 percent that 80
