40.67 is what percent of 57 - 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 57 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 57, so we can write it down as 100%=57.
4. We know, that x% equals 40.67 of the output value, so we can write it down as x%=40.67.
5. Now we have two simple equations:
1) 100%=57
2) x%=40.67
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%=57/40.67
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40.67 is what percent of 57

100%/x%=57/40.67
(100/x)*x=(57/40.67)*x       - we multiply both sides of the equation by x
100=1.4015244652078*x       - we divide both sides of the equation by (1.4015244652078) to get x
100/1.4015244652078=x
71.350877192982=x
x=71.350877192982

now we have:
40.67 is 71.350877192982% of 57
