17.55 is what percent of 18.2 - 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 18.2 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 18.2, so we can write it down as 100%=18.2.
4. We know, that x% equals 17.55 of the output value, so we can write it down as x%=17.55.
5. Now we have two simple equations:
1) 100%=18.2
2) x%=17.55
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%=18.2/17.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.55 is what percent of 18.2

100%/x%=18.2/17.55
(100/x)*x=(18.2/17.55)*x       - we multiply both sides of the equation by x
100=1.037037037037*x       - we divide both sides of the equation by (1.037037037037) to get x
100/1.037037037037=x
96.428571428571=x
x=96.428571428571

now we have:
17.55 is 96.428571428571% of 18.2
