109.2 is what percent of 143.7 - 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 143.7 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 143.7, so we can write it down as 100%=143.7.
4. We know, that x% equals 109.2 of the output value, so we can write it down as x%=109.2.
5. Now we have two simple equations:
1) 100%=143.7
2) x%=109.2
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%=143.7/109.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 109.2 is what percent of 143.7

100%/x%=143.7/109.2
(100/x)*x=(143.7/109.2)*x       - we multiply both sides of the equation by x
100=1.3159340659341*x       - we divide both sides of the equation by (1.3159340659341) to get x
100/1.3159340659341=x
75.991649269311=x
x=75.991649269311

now we have:
109.2 is 75.991649269311% of 143.7
