22.1 is what percent of 88.4 - 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 88.4 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 88.4, so we can write it down as 100%=88.4.
4. We know, that x% equals 22.1 of the output value, so we can write it down as x%=22.1.
5. Now we have two simple equations:
1) 100%=88.4
2) x%=22.1
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%=88.4/22.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 22.1 is what percent of 88.4

100%/x%=88.4/22.1
(100/x)*x=(88.4/22.1)*x       - we multiply both sides of the equation by x
100=4*x       - we divide both sides of the equation by (4) to get x
100/4=x
25=x
x=25

now we have:
22.1 is 25% of 88.4
