879.54 is what percent of 1143 - 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 1143 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 1143, so we can write it down as 100%=1143.
4. We know, that x% equals 879.54 of the output value, so we can write it down as x%=879.54.
5. Now we have two simple equations:
1) 100%=1143
2) x%=879.54
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%=1143/879.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 879.54 is what percent of 1143

100%/x%=1143/879.54
(100/x)*x=(1143/879.54)*x       - we multiply both sides of the equation by x
100=1.299542942902*x       - we divide both sides of the equation by (1.299542942902) to get x
100/1.299542942902=x
76.950131233596=x
x=76.950131233596

now we have:
879.54 is 76.950131233596% of 1143
