2.38 is what percent of 30 - 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 30 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 30, so we can write it down as 100%=30.
4. We know, that x% equals 2.38 of the output value, so we can write it down as x%=2.38.
5. Now we have two simple equations:
1) 100%=30
2) x%=2.38
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%=30/2.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.38 is what percent of 30

100%/x%=30/2.38
(100/x)*x=(30/2.38)*x       - we multiply both sides of the equation by x
100=12.605042016807*x       - we divide both sides of the equation by (12.605042016807) to get x
100/12.605042016807=x
7.9333333333333=x
x=7.9333333333333

now we have:
2.38 is 7.9333333333333% of 30
