17.8 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 17.8 of the output value, so we can write it down as x%=17.8.
5. Now we have two simple equations:
1) 100%=18.2
2) x%=17.8
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%=18.2/17.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.8 is what percent of 18.2

100%/x%=18.2/17.8
(100/x)*x=(18.2/17.8)*x       - we multiply both sides of the equation by x
100=1.0224719101124*x       - we divide both sides of the equation by (1.0224719101124) to get x
100/1.0224719101124=x
97.802197802198=x
x=97.802197802198

now we have:
17.8 is 97.802197802198% of 18.2
