685.75 is what percent of 650 - 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 650 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 650, so we can write it down as 100%=650.
4. We know, that x% equals 685.75 of the output value, so we can write it down as x%=685.75.
5. Now we have two simple equations:
1) 100%=650
2) x%=685.75
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%=650/685.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 685.75 is what percent of 650

100%/x%=650/685.75
(100/x)*x=(650/685.75)*x       - we multiply both sides of the equation by x
100=0.9478672985782*x       - we divide both sides of the equation by (0.9478672985782) to get x
100/0.9478672985782=x
105.5=x
x=105.5

now we have:
685.75 is 105.5% of 650
