21.54 is what percent of 29.97 - 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 29.97 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 29.97, so we can write it down as 100%=29.97.
4. We know, that x% equals 21.54 of the output value, so we can write it down as x%=21.54.
5. Now we have two simple equations:
1) 100%=29.97
2) x%=21.54
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%=29.97/21.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.54 is what percent of 29.97

100%/x%=29.97/21.54
(100/x)*x=(29.97/21.54)*x       - we multiply both sides of the equation by x
100=1.391364902507*x       - we divide both sides of the equation by (1.391364902507) to get x
100/1.391364902507=x
71.871871871872=x
x=71.871871871872

now we have:
21.54 is 71.871871871872% of 29.97
