2.42 is what percent of 18 - 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 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, so we can write it down as 100%=18.
4. We know, that x% equals 2.42 of the output value, so we can write it down as x%=2.42.
5. Now we have two simple equations:
1) 100%=18
2) x%=2.42
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%=18/2.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.42 is what percent of 18

100%/x%=18/2.42
(100/x)*x=(18/2.42)*x       - we multiply both sides of the equation by x
100=7.4380165289256*x       - we divide both sides of the equation by (7.4380165289256) to get x
100/7.4380165289256=x
13.444444444444=x
x=13.444444444444

now we have:
2.42 is 13.444444444444% of 18
