31.61 is what percent of 43.6 - 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 43.6 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 43.6, so we can write it down as 100%=43.6.
4. We know, that x% equals 31.61 of the output value, so we can write it down as x%=31.61.
5. Now we have two simple equations:
1) 100%=43.6
2) x%=31.61
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%=43.6/31.61
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.61 is what percent of 43.6

100%/x%=43.6/31.61
(100/x)*x=(43.6/31.61)*x       - we multiply both sides of the equation by x
100=1.3793103448276*x       - we divide both sides of the equation by (1.3793103448276) to get x
100/1.3793103448276=x
72.5=x
x=72.5

now we have:
31.61 is 72.5% of 43.6
