What is 11 percent of 3720 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 3720 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 3720 is 100%, so we can write it down as 3720=100%.
4. We know, that x is 11% of the output value, so we can write it down as x=11%.
5. Now we have two simple equations:
1) 3720=100%
2) x=11%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
3720/x=100%/11%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 11% of 3720

3720/x=100/11
(3720/x)*x=(100/11)*x       - we multiply both sides of the equation by x
3720=9.0909090909091*x       - we divide both sides of the equation by (9.0909090909091) to get x
3720/9.0909090909091=x
409.2=x
x=409.2

now we have:
11% of 3720=409.2
