28.74 is what percent of 17.5 - 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 17.5 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 17.5, so we can write it down as 100%=17.5.
4. We know, that x% equals 28.74 of the output value, so we can write it down as x%=28.74.
5. Now we have two simple equations:
1) 100%=17.5
2) x%=28.74
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%=17.5/28.74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.74 is what percent of 17.5

100%/x%=17.5/28.74
(100/x)*x=(17.5/28.74)*x       - we multiply both sides of the equation by x
100=0.6089074460682*x       - we divide both sides of the equation by (0.6089074460682) to get x
100/0.6089074460682=x
164.22857142857=x
x=164.22857142857

now we have:
28.74 is 164.22857142857% of 17.5
