What is 37.7 percent of 40.5 - 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 40.5 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 40.5 is 100%, so we can write it down as 40.5=100%.
4. We know, that x is 37.7% of the output value, so we can write it down as x=37.7%.
5. Now we have two simple equations:
1) 40.5=100%
2) x=37.7%
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:
40.5/x=100%/37.7%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 37.7% of 40.5

40.5/x=100/37.7
(40.5/x)*x=(100/37.7)*x       - we multiply both sides of the equation by x
40.5=2.6525198938992*x       - we divide both sides of the equation by (2.6525198938992) to get x
40.5/2.6525198938992=x
15.2685=x
x=15.2685

now we have:
37.7% of 40.5=15.2685
