You are watching: 9 is 15 of what number

As we have all the compelled values us need, now we can put them in a basic mathematical formula as below:

STEP 1 9 = 15% × Y

STEP 2 9 = 15/100× Y

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

STEP 3 Y = 9 × 100/15

STEP 4 Y = 9 × 100 ÷ 15

STEP 5 Y = 60

Finally, us have discovered the worth of Y i m sorry is 60 and also that is our answer.

You can easily calculate **9 is 15 percent that what number** by using any kind of regular calculator, simply enter **9 × 100 ÷ 15** and also you will gain your answer i beg your pardon is **60**

**Question:** her friend has a bag of marbles, and also he speak you the 15 percent of the marbles are red. If there room 9 red marbles. How countless marbles walk he have actually altogether?

**Answer:** 60 marbles.

**How To:** In this problem, we understand that the Percent is 15, and also we are likewise told the the component of the marbles is red, for this reason we know that the component is 9.

So, that means that it must be the total that"s missing. Here is the way to figure out what the complete is:

Part/Total = Percent/100

By utilizing a basic algebra we deserve to re-arrange our Percent equation prefer this:

Part × 100/Percent = Total

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

Let"s shot it the end on our problem around the marbles, that"s very basic and it"s simply two steps! We know that the "Part" (red marbles) is 9.

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

9 × 100 = 900

In step two, we take that 900 and divide it by the "Percent", i beg your pardon we space told is 15.

Again, it"s the "Total" that"s lacking here, and to uncover it, we just need to monitor our 2 action procedure together the vault problem.

Let"s assume the unknown worth is **Y**

First creating it as: **100% / Y = 15% / 9**

Drop the portion marks to leveling your calculations: **100 / Y = 15 / 9**

Multiply both political parties by Y to relocate Y on the best side of the equation: **100 = ( 15 / 9 ) Y**
