What is 30 percent of 15.207 - 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 15.207 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 15.207 is 100%, so we can write it down as 15.207=100%.
4. We know, that x is 30% of the output value, so we can write it down as x=30%.
5. Now we have two simple equations:
1) 15.207=100%
2) x=30%
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:
15.207/x=100%/30%
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 30% of 15.207

15.207/x=100/30
(15.207/x)*x=(100/30)*x       - we multiply both sides of the equation by x
15.207=3.3333333333333*x       - we divide both sides of the equation by (3.3333333333333) to get x
15.207/3.3333333333333=x
4.5621=x
x=4.5621

now we have:
30% of 15.207=4.5621
