55 is what percent of 159.3 - 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 159.3 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 159.3, so we can write it down as 100%=159.3.
4. We know, that x% equals 55 of the output value, so we can write it down as x%=55.
5. Now we have two simple equations:
1) 100%=159.3
2) x%=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%=159.3/55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55 is what percent of 159.3

100%/x%=159.3/55
(100/x)*x=(159.3/55)*x       - we multiply both sides of the equation by x
100=2.8963636363636*x       - we divide both sides of the equation by (2.8963636363636) to get x
100/2.8963636363636=x
34.526051475204=x
x=34.526051475204

now we have:
55 is 34.526051475204% of 159.3
