18.31 is what percent of 17.99 - 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 17.99 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 17.99, so we can write it down as 100%=17.99.
4. We know, that x% equals 18.31 of the output value, so we can write it down as x%=18.31.
5. Now we have two simple equations:
1) 100%=17.99
2) x%=18.31
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%=17.99/18.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.31 is what percent of 17.99

100%/x%=17.99/18.31
(100/x)*x=(17.99/18.31)*x       - we multiply both sides of the equation by x
100=0.98252321135991*x       - we divide both sides of the equation by (0.98252321135991) to get x
100/0.98252321135991=x
101.7787659811=x
x=101.7787659811

now we have:
18.31 is 101.7787659811% of 17.99
