154.2 is what percent of 158.8 - 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 158.8 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 158.8, so we can write it down as 100%=158.8.
4. We know, that x% equals 154.2 of the output value, so we can write it down as x%=154.2.
5. Now we have two simple equations:
1) 100%=158.8
2) x%=154.2
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%=158.8/154.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 154.2 is what percent of 158.8

100%/x%=158.8/154.2
(100/x)*x=(158.8/154.2)*x       - we multiply both sides of the equation by x
100=1.029831387808*x       - we divide both sides of the equation by (1.029831387808) to get x
100/1.029831387808=x
97.103274559194=x
x=97.103274559194

now we have:
154.2 is 97.103274559194% of 158.8
