We already have our first value **4** and the second value **20**. 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 = 4100

STEP 2 Y = 4100 × 20

STEP 3 Y = 4 ÷ 100 × 20

STEP 4 Y = 0.8

Finally, we have found the value of Y which is 0.8 and that is our answer.

If you want to use a calculator to know **what is 4 percent of 20**, simply enter **4 ÷ 100 × 20** and you will get your answer which is **0.8**

**Question:** At a high school 4 percent of seniors went on a mission trip. There were 20 seniors. How many seniors went on the trip?

**Answer:** 0.8 seniors went on the trip.

**Question:** 4 percent of the children in kindergarten like Thomas the Train. If there are 20 kids in kindergarten, how many of them like Thomas?

**Answer:** 0.8 kids like Thomas the Train.

Let's solve the equation for Y by first rewriting it as: **100% / 20 = 4% / Y**

Drop the percentage marks to simplify your calculations: **100 / 20 = 4 / Y**

Multiply both sides by Y to transfer it on the left side of the equation: **Y ( 100 / 20 ) = 4**

To isolate Y, multiply both sides by 20 / 100, we will have: **Y = 4 ( 20 / 100 )**

Computing the right side, we get: **Y = 0.8**

This leaves us with our final answer: **4% of 20 is 0.8**
