917.19 is what percent of 679.4 - 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 679.4 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 679.4, so we can write it down as 100%=679.4.
4. We know, that x% equals 917.19 of the output value, so we can write it down as x%=917.19.
5. Now we have two simple equations:
1) 100%=679.4
2) x%=917.19
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%=679.4/917.19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 917.19 is what percent of 679.4

100%/x%=679.4/917.19
(100/x)*x=(679.4/917.19)*x       - we multiply both sides of the equation by x
100=0.74074074074074*x       - we divide both sides of the equation by (0.74074074074074) to get x
100/0.74074074074074=x
135=x
x=135

now we have:
917.19 is 135% of 679.4
