457.78 is what percent of 603.5 - 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 603.5 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 603.5, so we can write it down as 100%=603.5.
4. We know, that x% equals 457.78 of the output value, so we can write it down as x%=457.78.
5. Now we have two simple equations:
1) 100%=603.5
2) x%=457.78
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%=603.5/457.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 457.78 is what percent of 603.5

100%/x%=603.5/457.78
(100/x)*x=(603.5/457.78)*x       - we multiply both sides of the equation by x
100=1.3183188431124*x       - we divide both sides of the equation by (1.3183188431124) to get x
100/1.3183188431124=x
75.854183927092=x
x=75.854183927092

now we have:
457.78 is 75.854183927092% of 603.5
