We assume, that the number 955 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 955 is 100%, so we can write it down as 955=100%.
4. We know, that x is 37% of the output value, so we can write it down as x=37%.
5. Now we have two simple equations:
1) 955=100%
2) x=37%
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:
955/x=100%/37%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
955/x=100/37
(955/x)*x=(100/37)*x - we multiply both sides of the equation by x
955=2.7027027027027*x - we divide both sides of the equation by (2.7027027027027) to get x
955/2.7027027027027=x
353.35=x
x=353.35
