28.2 is what percent of 158.4 - 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 158.4 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 158.4, so we can write it down as 100%=158.4.
4. We know, that x% equals 28.2 of the output value, so we can write it down as x%=28.2.
5. Now we have two simple equations:
1) 100%=158.4
2) x%=28.2
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%=158.4/28.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.2 is what percent of 158.4

100%/x%=158.4/28.2
(100/x)*x=(158.4/28.2)*x       - we multiply both sides of the equation by x
100=5.6170212765957*x       - we divide both sides of the equation by (5.6170212765957) to get x
100/5.6170212765957=x
17.80303030303=x
x=17.80303030303

now we have:
28.2 is 17.80303030303% of 158.4
