1.31 is what percent of 43.72 - 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 43.72 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 43.72, so we can write it down as 100%=43.72.
4. We know, that x% equals 1.31 of the output value, so we can write it down as x%=1.31.
5. Now we have two simple equations:
1) 100%=43.72
2) x%=1.31
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%=43.72/1.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.31 is what percent of 43.72

100%/x%=43.72/1.31
(100/x)*x=(43.72/1.31)*x       - we multiply both sides of the equation by x
100=33.374045801527*x       - we divide both sides of the equation by (33.374045801527) to get x
100/33.374045801527=x
2.996340347667=x
x=2.996340347667

now we have:
1.31 is 2.996340347667% of 43.72
