597.3 is what percent of 905 - 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 905 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 905, so we can write it down as 100%=905.
4. We know, that x% equals 597.3 of the output value, so we can write it down as x%=597.3.
5. Now we have two simple equations:
1) 100%=905
2) x%=597.3
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%=905/597.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 597.3 is what percent of 905

100%/x%=905/597.3
(100/x)*x=(905/597.3)*x       - we multiply both sides of the equation by x
100=1.5151515151515*x       - we divide both sides of the equation by (1.5151515151515) to get x
100/1.5151515151515=x
66=x
x=66

now we have:
597.3 is 66% of 905
