40.5 is what percent of 265 - 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 265 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 265, so we can write it down as 100%=265.
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%=265
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%=265/40.5
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 265

100%/x%=265/40.5
(100/x)*x=(265/40.5)*x       - we multiply both sides of the equation by x
100=6.5432098765432*x       - we divide both sides of the equation by (6.5432098765432) to get x
100/6.5432098765432=x
15.283018867925=x
x=15.283018867925

now we have:
40.5 is 15.283018867925% of 265
