13.73 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 13.73 of the output value, so we can write it down as x%=13.73.
5. Now we have two simple equations:
1) 100%=17.5
2) x%=13.73
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%=17.5/13.73
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.73 is what percent of 17.5

100%/x%=17.5/13.73
(100/x)*x=(17.5/13.73)*x       - we multiply both sides of the equation by x
100=1.2745812090313*x       - we divide both sides of the equation by (1.2745812090313) to get x
100/1.2745812090313=x
78.457142857143=x
x=78.457142857143

now we have:
13.73 is 78.457142857143% of 17.5
