## Step by action solution for calculating 12 is 80 percent that what number

We currently have our first value 12 and the 2nd value 80. Let"s i think the unknown value is Y i m sorry answer we will discover out.

You are watching: 12 is 80 percent of what number

As we have all the required values us need, currently we deserve to put them in a an easy mathematical formula as below:

STEP 112 = 80% × Y

STEP 212 = 80/100× Y

Multiplying both political parties by 100 and dividing both political parties of the equation by 80 we will certainly arrive at:

STEP 3Y = 12 × 100/80

STEP 4Y = 12 × 100 ÷ 80

STEP 5Y = 15

Finally, we have uncovered the value of Y i m sorry is 15 and that is ours answer.

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

## Sample questions, answers, and also how to

Question: your friend has a bag of marbles, and he tells you that 80 percent the the marbles room red. If there space 12 red marbles. How countless marbles does he have actually altogether?

How To: In this problem, we understand that the Percent is 80, and we are additionally told the the component of the marbles is red, therefore we recognize that the part is 12.

So, that way that it need to be the full that"s missing. Below is the method to number out what the complete is:

Part/Total = Percent/100

By utilizing a an easy algebra we have the right to re-arrange our Percent equation prefer this:

Part × 100/Percent = Total

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

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

So action one is to simply multiply that component by 100.

12 × 100 = 1200

In step two, we take the 1200 and also divide the by the "Percent", i beg your pardon we are told is 80.

So, 1200 separated by 80 = 15

And that way that the total number of marbles is 15.

Question: A high institution marching band has actually 12 flute players, If 80 percent of the band members pat the flute, climate how plenty of members space in the band?

Answer: There are 15 members in the band.

How To: The smaller "Part" in this trouble is 12 since there room 12 flute players and we room told the they comprise 80 percent of the band, therefore the "Percent" is 80.

Again, it"s the "Total" that"s lacking here, and also to find it, we simply need to follow our 2 action procedure as the ahead problem.

For action one, us multiply the "Part" by 100.

12 × 100 = 1200

For step two, we divide that 1200 by the "Percent", which is 80.

1200 separated by 80 equals 15

That means that the total number of band members is 15.

## Another step by step method

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

Step 2: very first writing it as: 100% / Y = 80% / 12

Step 3: drop the percentage marks to leveling your calculations: 100 / Y = 80 / 12

Step 4: multiply both sides by Y to relocate Y top top the ideal side that the equation: 100 = ( 80 / 12 ) Y

Step 5: simple the best side, us get: 100 = 80 Y

Step 6: splitting both political parties of the equation through 80, we will certainly arrive at 15 = Y

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