408.93 is what percent of 550 - 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 550 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 550, so we can write it down as 100%=550.
4. We know, that x% equals 408.93 of the output value, so we can write it down as x%=408.93.
5. Now we have two simple equations:
1) 100%=550
2) x%=408.93
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%=550/408.93
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 408.93 is what percent of 550

100%/x%=550/408.93
(100/x)*x=(550/408.93)*x       - we multiply both sides of the equation by x
100=1.3449734673416*x       - we divide both sides of the equation by (1.3449734673416) to get x
100/1.3449734673416=x
74.350909090909=x
x=74.350909090909

now we have:
408.93 is 74.350909090909% of 550
