40.5 is what percent of 73.5 - 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 73.5 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 100% equals 73.5, so we can write it down as 100%=73.5.
4. We know, that x% equals 40.5 of the output value, so we can write it down as x%=40.5.
5. Now we have two simple equations:
1) 100%=73.5
2) x%=40.5
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%=73.5/40.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40.5 is what percent of 73.5

100%/x%=73.5/40.5
(100/x)*x=(73.5/40.5)*x       - we multiply both sides of the equation by x
100=1.8148148148148*x       - we divide both sides of the equation by (1.8148148148148) to get x
100/1.8148148148148=x
55.102040816327=x
x=55.102040816327

now we have:
40.5 is 55.102040816327% of 73.5
