907.8 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 907.8 of the output value, so we can write it down as x%=907.8.
5. Now we have two simple equations:
1) 100%=1010
2) x%=907.8
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%=1010/907.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 907.8 is what percent of 1010

100%/x%=1010/907.8
(100/x)*x=(1010/907.8)*x       - we multiply both sides of the equation by x
100=1.112579863406*x       - we divide both sides of the equation by (1.112579863406) to get x
100/1.112579863406=x
89.881188118812=x
x=89.881188118812

now we have:
907.8 is 89.881188118812% of 1010
