779.8 is what percent of 920 - 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 920 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 920, so we can write it down as 100%=920.
4. We know, that x% equals 779.8 of the output value, so we can write it down as x%=779.8.
5. Now we have two simple equations:
1) 100%=920
2) x%=779.8
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%=920/779.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 779.8 is what percent of 920

100%/x%=920/779.8
(100/x)*x=(920/779.8)*x       - we multiply both sides of the equation by x
100=1.179789689664*x       - we divide both sides of the equation by (1.179789689664) to get x
100/1.179789689664=x
84.760869565217=x
x=84.760869565217

now we have:
779.8 is 84.760869565217% of 920
