We already have our first value **20** and the second value **18**. Let's assume the unknown value is **Y** which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1 Y = 20100

STEP 2 Y = 20100 × 18

STEP 3 Y = 20 ÷ 100 × 18

STEP 4 Y = 3.6

Finally, we have found the value of Y which is 3.6 and that is our answer.

If you want to use a calculator to know **what is 20 percent of 18**, simply enter **20 ÷ 100 × 18** and you will get your answer which is **3.6**

**Question:** At a high school 20 percent of seniors went on a mission trip. There were 18 seniors. How many seniors went on the trip?

**Answer:** 3.6 seniors went on the trip.

**Question:** 20 percent of the children in kindergarten like Thomas the Train. If there are 18 kids in kindergarten, how many of them like Thomas?

**Answer:** 3.6 kids like Thomas the Train.

Let's solve the equation for Y by first rewriting it as: **100% / 18 = 20% / Y**

Drop the percentage marks to simplify your calculations: **100 / 18 = 20 / Y**

Multiply both sides by Y to transfer it on the left side of the equation: **Y ( 100 / 18 ) = 20**

To isolate Y, multiply both sides by 18 / 100, we will have: **Y = 20 ( 18 / 100 )**

Computing the right side, we get: **Y = 3.6**

This leaves us with our final answer: **20% of 18 is 3.6**
