88.4 is what percent of 66 - 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 66 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 66, so we can write it down as 100%=66.
4. We know, that x% equals 88.4 of the output value, so we can write it down as x%=88.4.
5. Now we have two simple equations:
1) 100%=66
2) x%=88.4
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%=66/88.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 88.4 is what percent of 66

100%/x%=66/88.4
(100/x)*x=(66/88.4)*x       - we multiply both sides of the equation by x
100=0.74660633484163*x       - we divide both sides of the equation by (0.74660633484163) to get x
100/0.74660633484163=x
133.93939393939=x
x=133.93939393939

now we have:
88.4 is 133.93939393939% of 66
