17.7 is what percent of 45.85 - 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 45.85 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 45.85, so we can write it down as 100%=45.85.
4. We know, that x% equals 17.7 of the output value, so we can write it down as x%=17.7.
5. Now we have two simple equations:
1) 100%=45.85
2) x%=17.7
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%=45.85/17.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.7 is what percent of 45.85

100%/x%=45.85/17.7
(100/x)*x=(45.85/17.7)*x       - we multiply both sides of the equation by x
100=2.590395480226*x       - we divide both sides of the equation by (2.590395480226) to get x
100/2.590395480226=x
38.604143947655=x
x=38.604143947655

now we have:
17.7 is 38.604143947655% of 45.85
