189.66 is what percent of 139.2 - 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 139.2 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 139.2, so we can write it down as 100%=139.2.
4. We know, that x% equals 189.66 of the output value, so we can write it down as x%=189.66.
5. Now we have two simple equations:
1) 100%=139.2
2) x%=189.66
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%=139.2/189.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 189.66 is what percent of 139.2

100%/x%=139.2/189.66
(100/x)*x=(139.2/189.66)*x       - we multiply both sides of the equation by x
100=0.73394495412844*x       - we divide both sides of the equation by (0.73394495412844) to get x
100/0.73394495412844=x
136.25=x
x=136.25

now we have:
189.66 is 136.25% of 139.2
