45.9 is what percent of 170 - 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 170 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 170, so we can write it down as 100%=170.
4. We know, that x% equals 45.9 of the output value, so we can write it down as x%=45.9.
5. Now we have two simple equations:
1) 100%=170
2) x%=45.9
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%=170/45.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 45.9 is what percent of 170

100%/x%=170/45.9
(100/x)*x=(170/45.9)*x       - we multiply both sides of the equation by x
100=3.7037037037037*x       - we divide both sides of the equation by (3.7037037037037) to get x
100/3.7037037037037=x
27=x
x=27

now we have:
45.9 is 27% of 170
