## Step by step solution for calculating 15 is 30 percent of what number

We already have our initially worth 15 and the second value 30. Let"s assume the unrecognized worth is Y which answer we will find out.

You are watching: 15 is 30 percent of what

As we have all the required worths we require, Now we can put them in a straightforward mathematical formula as below:

STEP 1 15 = 30% × Y

STEP 2 15 = 30/100× Y

Multiplying both sides by 100 and also splitting both sides of the equation by 30 we will arrive at:

STEP 3 Y = 15 × 100/30

STEP 4 Y = 15 × 100 ÷ 30

STEP 5 Y = 50

Finally, we have actually found the worth of Y which is 50 and also that is our answer.

You deserve to conveniently calculate 15 is 30 percent of what number by utilizing any type of consistent calculator, ssuggest enter 15 × 100 ÷ 30 and also you will certainly obtain your answer which is 50

## Sample concerns, answers, and also exactly how to

Question: Your friend has actually a bag of marbles, and also he tells you that 30 percent of the marbles are red. If there are 15 red marbles. How many marbles does he have altogether?

How To: In this problem, we understand that the Percent is 30, and we are additionally told that the Part of the marbles is red, so we recognize that the Part is 15.

So, that means that it should be the Total that"s absent. Here is the way to figure out what the Total is:

Part/Total = Percent/100

By making use of a simple algebra we can re-ararray 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 certainly acquire the "Total".

Let"s attempt it out on our problem around the marbles, that"s exceptionally simple and also it"s simply 2 steps! We recognize that the "Part" (red marbles) is 15.

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

15 × 100 = 1500

In action 2, we take that 1500 and divide it by the "Percent", which we are told is 30.

So, 1500 separated by 30 = 50

And that means that the full number of marbles is 50.

Question: A high college marching band has actually 15 flute players, If 30 percent of the band also members play the flute, then how many type of members are in the band?

Answer: There are 50 members in the band also.

How To: The smaller "Part" in this difficulty is 15 since there are 15 flute players and we are told that they make up 30 percent of the band, so the "Percent" is 30.

Again, it"s the "Total" that"s missing here, and to discover it, we just must follow our 2 step procedure as the previous difficulty.

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

15 × 100 = 1500

For step 2, we divide that 1500 by the "Percent", which is 30.

1500 separated by 30 equates to 50

That indicates that the total variety of band also members is 50.

## Have time and want to learn the calculation?

Let"s assume the unwell-known worth is Y

First writing it as: 100% / Y = 30% / 15

Drop the percent marks to simplify your calculations: 100 / Y = 30 / 15

Multiply both sides by Y to relocate Y on the right side of the equation: 100 = ( 30 / 15 ) Y
