133.2 is what percent of 119.88 - 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 119.88 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 119.88, so we can write it down as 100%=119.88.
4. We know, that x% equals 133.2 of the output value, so we can write it down as x%=133.2.
5. Now we have two simple equations:
1) 100%=119.88
2) x%=133.2
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%=119.88/133.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 133.2 is what percent of 119.88

100%/x%=119.88/133.2
(100/x)*x=(119.88/133.2)*x       - we multiply both sides of the equation by x
100=0.9*x       - we divide both sides of the equation by (0.9) to get x
100/0.9=x
111.11111111111=x
x=111.11111111111

now we have:
133.2 is 111.11111111111% of 119.88
