164.4 is what percent of 40 - 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 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 40, so we can write it down as 100%=40.
4. We know, that x% equals 164.4 of the output value, so we can write it down as x%=164.4.
5. Now we have two simple equations:
1) 100%=40
2) x%=164.4
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%=40/164.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 164.4 is what percent of 40

100%/x%=40/164.4
(100/x)*x=(40/164.4)*x       - we multiply both sides of the equation by x
100=0.24330900243309*x       - we divide both sides of the equation by (0.24330900243309) to get x
100/0.24330900243309=x
411=x
x=411

now we have:
164.4 is 411% of 40
