What is 61.4 percent of 15 - 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 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 is 100%, so we can write it down as 15=100%.
4. We know, that x is 61.4% of the output value, so we can write it down as x=61.4%.
5. Now we have two simple equations:
1) 15=100%
2) x=61.4%
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/x=100%/61.4%
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 61.4% of 15

15/x=100/61.4
(15/x)*x=(100/61.4)*x       - we multiply both sides of the equation by x
15=1.628664495114*x       - we divide both sides of the equation by (1.628664495114) to get x
15/1.628664495114=x
9.21=x
x=9.21

now we have:
61.4% of 15=9.21
