21.59 is what percent of 43.45 - 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 43.45 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 43.45, so we can write it down as 100%=43.45.
4. We know, that x% equals 21.59 of the output value, so we can write it down as x%=21.59.
5. Now we have two simple equations:
1) 100%=43.45
2) x%=21.59
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%=43.45/21.59
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.59 is what percent of 43.45

100%/x%=43.45/21.59
(100/x)*x=(43.45/21.59)*x       - we multiply both sides of the equation by x
100=2.0125057897175*x       - we divide both sides of the equation by (2.0125057897175) to get x
100/2.0125057897175=x
49.689298043728=x
x=49.689298043728

now we have:
21.59 is 49.689298043728% of 43.45
