21.03 is what percent of 560.8 - 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 560.8 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 560.8, so we can write it down as 100%=560.8.
4. We know, that x% equals 21.03 of the output value, so we can write it down as x%=21.03.
5. Now we have two simple equations:
1) 100%=560.8
2) x%=21.03
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%=560.8/21.03
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.03 is what percent of 560.8

100%/x%=560.8/21.03
(100/x)*x=(560.8/21.03)*x       - we multiply both sides of the equation by x
100=26.666666666667*x       - we divide both sides of the equation by (26.666666666667) to get x
100/26.666666666667=x
3.75=x
x=3.75

now we have:
21.03 is 3.75% of 560.8
