What is 66.96 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 66.96% of the output value, so we can write it down as x=66.96%.
5. Now we have two simple equations:
1) 15=100%
2) x=66.96%
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%/66.96%
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 66.96% of 15

15/x=100/66.96
(15/x)*x=(100/66.96)*x       - we multiply both sides of the equation by x
15=1.4934289127838*x       - we divide both sides of the equation by (1.4934289127838) to get x
15/1.4934289127838=x
10.044=x
x=10.044

now we have:
66.96% of 15=10.044
