What is 40.9 percent of 43.13 - 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 43.13 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 43.13 is 100%, so we can write it down as 43.13=100%.
4. We know, that x is 40.9% of the output value, so we can write it down as x=40.9%.
5. Now we have two simple equations:
1) 43.13=100%
2) x=40.9%
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:
43.13/x=100%/40.9%
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 40.9% of 43.13

43.13/x=100/40.9
(43.13/x)*x=(100/40.9)*x       - we multiply both sides of the equation by x
43.13=2.4449877750611*x       - we divide both sides of the equation by (2.4449877750611) to get x
43.13/2.4449877750611=x
17.64017=x
x=17.64017

now we have:
40.9% of 43.13=17.64017
