837.5 is what percent of 980 - 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 980 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 980, so we can write it down as 100%=980.
4. We know, that x% equals 837.5 of the output value, so we can write it down as x%=837.5.
5. Now we have two simple equations:
1) 100%=980
2) x%=837.5
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%=980/837.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 837.5 is what percent of 980

100%/x%=980/837.5
(100/x)*x=(980/837.5)*x       - we multiply both sides of the equation by x
100=1.1701492537313*x       - we divide both sides of the equation by (1.1701492537313) to get x
100/1.1701492537313=x
85.459183673469=x
x=85.459183673469

now we have:
837.5 is 85.459183673469% of 980
