What is 13.33333 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 30 is 100%, so we can write it down as 30=100%.
4. We know, that x is 13.33333% of the output value, so we can write it down as x=13.33333%.
5. Now we have two simple equations:
1) 30=100%
2) x=13.33333%
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:
30/x=100%/13.33333%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 13.33333% of 30

30/x=100/13.33333
(30/x)*x=(100/13.33333)*x       - we multiply both sides of the equation by x
30=7.5000018750005*x       - we divide both sides of the equation by (7.5000018750005) to get x
30/7.5000018750005=x
3.999999=x
x=3.999999

now we have:
13.33333% of 30=3.999999
