958.6 is what percent of 990 - 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 990 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 990, so we can write it down as 100%=990.
4. We know, that x% equals 958.6 of the output value, so we can write it down as x%=958.6.
5. Now we have two simple equations:
1) 100%=990
2) x%=958.6
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%=990/958.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 958.6 is what percent of 990

100%/x%=990/958.6
(100/x)*x=(990/958.6)*x       - we multiply both sides of the equation by x
100=1.0327561026497*x       - we divide both sides of the equation by (1.0327561026497) to get x
100/1.0327561026497=x
96.828282828283=x
x=96.828282828283

now we have:
958.6 is 96.828282828283% of 990
