We already have our first value 10 and the second value 400. 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 = 10100
STEP 2 Y = 10100 × 400
STEP 3 Y = 10 ÷ 100 × 400
STEP 4 Y = 40
Finally, we have found the value of Y which is 40 and that is our answer.
If you want to use a calculator to know what is 10 percent of 400, simply enter 10 ÷ 100 × 400 and you will get your answer which is 40

Question: At a high school 10 percent of seniors went on a mission trip. There were 400 seniors. How many seniors went on the trip?
Answer: 40 seniors went on the trip.
Question: 10 percent of the children in kindergarten like Thomas the Train. If there are 400 kids in kindergarten, how many of them like Thomas?
Answer: 40 kids like Thomas the Train.
Let's solve the equation for Y by first rewriting it as: 100% / 400 = 10% / Y
Drop the percentage marks to simplify your calculations: 100 / 400 = 10 / Y
Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 400 ) = 10
To isolate Y, multiply both sides by 400 / 100, we will have: Y = 10 ( 400 / 100 )
Computing the right side, we get: Y = 40
This leaves us with our final answer: 10% of 400 is 40
