17.9 is what percent of 93 - 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 93 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 93, so we can write it down as 100%=93.
4. We know, that x% equals 17.9 of the output value, so we can write it down as x%=17.9.
5. Now we have two simple equations:
1) 100%=93
2) x%=17.9
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%=93/17.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.9 is what percent of 93

100%/x%=93/17.9
(100/x)*x=(93/17.9)*x       - we multiply both sides of the equation by x
100=5.195530726257*x       - we divide both sides of the equation by (5.195530726257) to get x
100/5.195530726257=x
19.247311827957=x
x=19.247311827957

now we have:
17.9 is 19.247311827957% of 93
