87.45 is what percent of 144 - 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 144 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 144, so we can write it down as 100%=144.
4. We know, that x% equals 87.45 of the output value, so we can write it down as x%=87.45.
5. Now we have two simple equations:
1) 100%=144
2) x%=87.45
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%=144/87.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87.45 is what percent of 144

100%/x%=144/87.45
(100/x)*x=(144/87.45)*x       - we multiply both sides of the equation by x
100=1.6466552315609*x       - we divide both sides of the equation by (1.6466552315609) to get x
100/1.6466552315609=x
60.729166666667=x
x=60.729166666667

now we have:
87.45 is 60.729166666667% of 144
