687.5 is what percent of 1010 - 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 1010 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 1010, so we can write it down as 100%=1010.
4. We know, that x% equals 687.5 of the output value, so we can write it down as x%=687.5.
5. Now we have two simple equations:
1) 100%=1010
2) x%=687.5
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%=1010/687.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 687.5 is what percent of 1010

100%/x%=1010/687.5
(100/x)*x=(1010/687.5)*x       - we multiply both sides of the equation by x
100=1.4690909090909*x       - we divide both sides of the equation by (1.4690909090909) to get x
100/1.4690909090909=x
68.069306930693=x
x=68.069306930693

now we have:
687.5 is 68.069306930693% of 1010
