17 is what percent of 37.7 - 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 37.7 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 37.7, so we can write it down as 100%=37.7.
4. We know, that x% equals 17 of the output value, so we can write it down as x%=17.
5. Now we have two simple equations:
1) 100%=37.7
2) x%=17
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%=37.7/17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17 is what percent of 37.7

100%/x%=37.7/17
(100/x)*x=(37.7/17)*x       - we multiply both sides of the equation by x
100=2.2176470588235*x       - we divide both sides of the equation by (2.2176470588235) to get x
100/2.2176470588235=x
45.092838196286=x
x=45.092838196286

now we have:
17 is 45.092838196286% of 37.7
