17.39 is what percent of 133.89 - 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 133.89 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 133.89, so we can write it down as 100%=133.89.
4. We know, that x% equals 17.39 of the output value, so we can write it down as x%=17.39.
5. Now we have two simple equations:
1) 100%=133.89
2) x%=17.39
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%=133.89/17.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.39 is what percent of 133.89

100%/x%=133.89/17.39
(100/x)*x=(133.89/17.39)*x       - we multiply both sides of the equation by x
100=7.6992524439333*x       - we divide both sides of the equation by (7.6992524439333) to get x
100/7.6992524439333=x
12.988273956233=x
x=12.988273956233

now we have:
17.39 is 12.988273956233% of 133.89
