40 is what percent of 1113 - 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 1113 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 100% equals 1113, so we can write it down as 100%=1113.
4. We know, that x% equals 40 of the output value, so we can write it down as x%=40.
5. Now we have two simple equations:
1) 100%=1113
2) x%=40
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:
100%/x%=1113/40
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40 is what percent of 1113

100%/x%=1113/40
(100/x)*x=(1113/40)*x       - we multiply both sides of the equation by x
100=27.825*x       - we divide both sides of the equation by (27.825) to get x
100/27.825=x
3.5938903863432=x
x=3.5938903863432

now we have:
40 is 3.5938903863432% of 1113
