88 is what percent of 123.2 - 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 123.2 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 123.2, so we can write it down as 100%=123.2.
4. We know, that x% equals 88 of the output value, so we can write it down as x%=88.
5. Now we have two simple equations:
1) 100%=123.2
2) x%=88
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%=123.2/88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 88 is what percent of 123.2

100%/x%=123.2/88
(100/x)*x=(123.2/88)*x       - we multiply both sides of the equation by x
100=1.4*x       - we divide both sides of the equation by (1.4) to get x
100/1.4=x
71.428571428571=x
x=71.428571428571

now we have:
88 is 71.428571428571% of 123.2
