We already have our first value 4 and the second value 21. 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 × 21
STEP 3 Y = 4 ÷ 100 × 21
STEP 4 Y = 0.84
Finally, we have found the value of Y which is 0.84 and that is our answer.
If you want to use a calculator to know what is 4 percent of 21, simply enter 4 ÷ 100 × 21 and you will get your answer which is 0.84

Question: At a high school 4 percent of seniors went on a mission trip. There were 21 seniors. How many seniors went on the trip?
Answer: 0.84 seniors went on the trip.
Question: 4 percent of the children in kindergarten like Thomas the Train. If there are 21 kids in kindergarten, how many of them like Thomas?
Answer: 0.84 kids like Thomas the Train.
Let's solve the equation for Y by first rewriting it as: 100% / 21 = 4% / Y
Drop the percentage marks to simplify your calculations: 100 / 21 = 4 / Y
Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 21 ) = 4
To isolate Y, multiply both sides by 21 / 100, we will have: Y = 4 ( 21 / 100 )
Computing the right side, we get: Y = 0.84
This leaves us with our final answer: 4% of 21 is 0.84
