143.28 is what percent of 149.25 - 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 149.25 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 149.25, so we can write it down as 100%=149.25.
4. We know, that x% equals 143.28 of the output value, so we can write it down as x%=143.28.
5. Now we have two simple equations:
1) 100%=149.25
2) x%=143.28
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%=149.25/143.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 143.28 is what percent of 149.25

100%/x%=149.25/143.28
(100/x)*x=(149.25/143.28)*x       - we multiply both sides of the equation by x
100=1.0416666666667*x       - we divide both sides of the equation by (1.0416666666667) to get x
100/1.0416666666667=x
96=x
x=96

now we have:
143.28 is 96% of 149.25
