987.5 is what percent of 1031 - 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 1031 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 1031, so we can write it down as 100%=1031.
4. We know, that x% equals 987.5 of the output value, so we can write it down as x%=987.5.
5. Now we have two simple equations:
1) 100%=1031
2) x%=987.5
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%=1031/987.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 987.5 is what percent of 1031

100%/x%=1031/987.5
(100/x)*x=(1031/987.5)*x       - we multiply both sides of the equation by x
100=1.0440506329114*x       - we divide both sides of the equation by (1.0440506329114) to get x
100/1.0440506329114=x
95.780795344326=x
x=95.780795344326

now we have:
987.5 is 95.780795344326% of 1031
