30.6 is what percent of 159.8 - 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 159.8 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 159.8, so we can write it down as 100%=159.8.
4. We know, that x% equals 30.6 of the output value, so we can write it down as x%=30.6.
5. Now we have two simple equations:
1) 100%=159.8
2) x%=30.6
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%=159.8/30.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.6 is what percent of 159.8

100%/x%=159.8/30.6
(100/x)*x=(159.8/30.6)*x       - we multiply both sides of the equation by x
100=5.2222222222222*x       - we divide both sides of the equation by (5.2222222222222) to get x
100/5.2222222222222=x
19.148936170213=x
x=19.148936170213

now we have:
30.6 is 19.148936170213% of 159.8
