40.75 is what percent of 355 - 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 355 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 355, so we can write it down as 100%=355.
4. We know, that x% equals 40.75 of the output value, so we can write it down as x%=40.75.
5. Now we have two simple equations:
1) 100%=355
2) x%=40.75
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%=355/40.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40.75 is what percent of 355

100%/x%=355/40.75
(100/x)*x=(355/40.75)*x       - we multiply both sides of the equation by x
100=8.7116564417178*x       - we divide both sides of the equation by (8.7116564417178) to get x
100/8.7116564417178=x
11.478873239437=x
x=11.478873239437

now we have:
40.75 is 11.478873239437% of 355
