28.2 is what percent of 136 - 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 136 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 136, so we can write it down as 100%=136.
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%=136
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%=136/28.2
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 136

100%/x%=136/28.2
(100/x)*x=(136/28.2)*x       - we multiply both sides of the equation by x
100=4.822695035461*x       - we divide both sides of the equation by (4.822695035461) to get x
100/4.822695035461=x
20.735294117647=x
x=20.735294117647

now we have:
28.2 is 20.735294117647% of 136
