37.99 is what percent of 300 - 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 300 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 300, so we can write it down as 100%=300.
4. We know, that x% equals 37.99 of the output value, so we can write it down as x%=37.99.
5. Now we have two simple equations:
1) 100%=300
2) x%=37.99
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%=300/37.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 37.99 is what percent of 300

100%/x%=300/37.99
(100/x)*x=(300/37.99)*x       - we multiply both sides of the equation by x
100=7.896814951303*x       - we divide both sides of the equation by (7.896814951303) to get x
100/7.896814951303=x
12.663333333333=x
x=12.663333333333

now we have:
37.99 is 12.663333333333% of 300
