3.6 is what percent of 142.2 - 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 142.2 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 142.2, so we can write it down as 100%=142.2.
4. We know, that x% equals 3.6 of the output value, so we can write it down as x%=3.6.
5. Now we have two simple equations:
1) 100%=142.2
2) x%=3.6
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%=142.2/3.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.6 is what percent of 142.2

100%/x%=142.2/3.6
(100/x)*x=(142.2/3.6)*x       - we multiply both sides of the equation by x
100=39.5*x       - we divide both sides of the equation by (39.5) to get x
100/39.5=x
2.5316455696203=x
x=2.5316455696203

now we have:
3.6 is 2.5316455696203% of 142.2
