659.5 is what percent of 685 - 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 685 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 685, so we can write it down as 100%=685.
4. We know, that x% equals 659.5 of the output value, so we can write it down as x%=659.5.
5. Now we have two simple equations:
1) 100%=685
2) x%=659.5
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%=685/659.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 659.5 is what percent of 685

100%/x%=685/659.5
(100/x)*x=(685/659.5)*x       - we multiply both sides of the equation by x
100=1.0386656557998*x       - we divide both sides of the equation by (1.0386656557998) to get x
100/1.0386656557998=x
96.277372262774=x
x=96.277372262774

now we have:
659.5 is 96.277372262774% of 685
