We already have our first value 400 and the second value 72. 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 = 72/400
STEP 2 Y = 72/400 × 100/100 = 18/100
STEP 3 Y = 18
Finally, we have found the value of Y which is 18 and that is our answer.
You can use a calculator to find what percent of 400 is 72, just enter 72 ÷ 400 × 100 and you will get your answer which is 18

Here is a calculator to solve percentage calculations such as what percent of 400 is 72. You can solve this type of calculation with your values by entering them into the calculator's fields, and click 'Calculate' to get the result and explanation.
Let's solve the equation for Y by first rewriting it as: 100% / 400 = Y% / 72
Drop the percentage marks to simplify your calculations: 100 / 400 = Y / 72
Multiply both sides by 72 to isolate Y on the right side of the equation: 72 ( 100 / 400 ) = Y
Computing the left side, we get: 18 = Y
This leaves us with our final answer: 18 percent of 400 is 72
