997.6 is what percent of 1089 - 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 1089 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 1089, so we can write it down as 100%=1089.
4. We know, that x% equals 997.6 of the output value, so we can write it down as x%=997.6.
5. Now we have two simple equations:
1) 100%=1089
2) x%=997.6
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%=1089/997.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 997.6 is what percent of 1089

100%/x%=1089/997.6
(100/x)*x=(1089/997.6)*x       - we multiply both sides of the equation by x
100=1.0916198877306*x       - we divide both sides of the equation by (1.0916198877306) to get x
100/1.0916198877306=x
91.606978879706=x
x=91.606978879706

now we have:
997.6 is 91.606978879706% of 1089
