You are watching: 18 is 9 of what number

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

STEP 1 18 = 9% × Y

STEP 2 18 = 9/100× Y

Multiplying both political parties by 100 and also dividing both sides of the equation through 9 we will certainly arrive at:

STEP 3 Y = 18 × 100/9

STEP 4 Y = 18 × 100 ÷ 9

STEP 5 Y = 200

Finally, we have found the worth of Y i m sorry is 200 and also that is our answer.

You can easily calculate **18 is 9 percent the what number** through using any kind of regular calculator, simply go into **18 × 100 ÷ 9** and also you will acquire your answer i m sorry is **200**

## Sample questions, answers, and how to

**Question:** your friend has a bag the marbles, and also he tells you the 9 percent of the marbles are red. If there are 18 red marbles. How numerous marbles go he have actually altogether?

**Answer:** 200 marbles.

**How To:** In this problem, we know that the Percent is 9, and also we are also told the the component of the marbles is red, so we recognize that the part is 18.

So, that method that it have to be the complete that"s missing. Below is the means to number out what the total is:

Part/Total = Percent/100

By making use of a basic algebra we deserve to re-arrange our Percent equation favor this:

Part × 100/Percent = Total

If us take the "Part" and also multiply the by 100, and 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 an easy and it"s just two steps! We know that the "Part" (red marbles) is 18.

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

18 × 100 = 1800

In step two, us take the 1800 and also divide that by the "Percent", i beg your pardon we room told is 9.

So, 1800 split by 9 = 200
