21.6 is what percent of 88 - 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 88 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 88, so we can write it down as 100%=88.
4. We know, that x% equals 21.6 of the output value, so we can write it down as x%=21.6.
5. Now we have two simple equations:
1) 100%=88
2) x%=21.6
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%=88/21.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.6 is what percent of 88

100%/x%=88/21.6
(100/x)*x=(88/21.6)*x       - we multiply both sides of the equation by x
100=4.0740740740741*x       - we divide both sides of the equation by (4.0740740740741) to get x
100/4.0740740740741=x
24.545454545455=x
x=24.545454545455

now we have:
21.6 is 24.545454545455% of 88
