2.07 is what percent of 40 - 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 40 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 40, so we can write it down as 100%=40.
4. We know, that x% equals 2.07 of the output value, so we can write it down as x%=2.07.
5. Now we have two simple equations:
1) 100%=40
2) x%=2.07
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%=40/2.07
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.07 is what percent of 40

100%/x%=40/2.07
(100/x)*x=(40/2.07)*x       - we multiply both sides of the equation by x
100=19.323671497585*x       - we divide both sides of the equation by (19.323671497585) to get x
100/19.323671497585=x
5.175=x
x=5.175

now we have:
2.07 is 5.175% of 40
