143.55 is what percent of 957 - 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 957 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 957, so we can write it down as 100%=957.
4. We know, that x% equals 143.55 of the output value, so we can write it down as x%=143.55.
5. Now we have two simple equations:
1) 100%=957
2) x%=143.55
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%=957/143.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 143.55 is what percent of 957

100%/x%=957/143.55
(100/x)*x=(957/143.55)*x       - we multiply both sides of the equation by x
100=6.6666666666667*x       - we divide both sides of the equation by (6.6666666666667) to get x
100/6.6666666666667=x
15=x
x=15

now we have:
143.55 is 15% of 957
