972.5 is what percent of 1285 - 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 1285 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 1285, so we can write it down as 100%=1285.
4. We know, that x% equals 972.5 of the output value, so we can write it down as x%=972.5.
5. Now we have two simple equations:
1) 100%=1285
2) x%=972.5
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%=1285/972.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 972.5 is what percent of 1285

100%/x%=1285/972.5
(100/x)*x=(1285/972.5)*x       - we multiply both sides of the equation by x
100=1.3213367609254*x       - we divide both sides of the equation by (1.3213367609254) to get x
100/1.3213367609254=x
75.68093385214=x
x=75.68093385214

now we have:
972.5 is 75.68093385214% of 1285
