40.45 is what percent of 50.18 - 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 50.18 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 50.18, so we can write it down as 100%=50.18.
4. We know, that x% equals 40.45 of the output value, so we can write it down as x%=40.45.
5. Now we have two simple equations:
1) 100%=50.18
2) x%=40.45
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%=50.18/40.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40.45 is what percent of 50.18

100%/x%=50.18/40.45
(100/x)*x=(50.18/40.45)*x       - we multiply both sides of the equation by x
100=1.240543881335*x       - we divide both sides of the equation by (1.240543881335) to get x
100/1.240543881335=x
80.609804703069=x
x=80.609804703069

now we have:
40.45 is 80.609804703069% of 50.18
