387.54 is what percent of 490.25 - 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 490.25 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 490.25, so we can write it down as 100%=490.25.
4. We know, that x% equals 387.54 of the output value, so we can write it down as x%=387.54.
5. Now we have two simple equations:
1) 100%=490.25
2) x%=387.54
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%=490.25/387.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 387.54 is what percent of 490.25

100%/x%=490.25/387.54
(100/x)*x=(490.25/387.54)*x       - we multiply both sides of the equation by x
100=1.2650307065077*x       - we divide both sides of the equation by (1.2650307065077) to get x
100/1.2650307065077=x
79.049464558899=x
x=79.049464558899

now we have:
387.54 is 79.049464558899% of 490.25
