388.91 is what percent of 573 - 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 573 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 573, so we can write it down as 100%=573.
4. We know, that x% equals 388.91 of the output value, so we can write it down as x%=388.91.
5. Now we have two simple equations:
1) 100%=573
2) x%=388.91
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%=573/388.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 388.91 is what percent of 573

100%/x%=573/388.91
(100/x)*x=(573/388.91)*x       - we multiply both sides of the equation by x
100=1.473348589648*x       - we divide both sides of the equation by (1.473348589648) to get x
100/1.473348589648=x
67.87260034904=x
x=67.87260034904

now we have:
388.91 is 67.87260034904% of 573
