What is 61 percent of 12.99 - 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 12.99 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 12.99 is 100%, so we can write it down as 12.99=100%.
4. We know, that x is 61% of the output value, so we can write it down as x=61%.
5. Now we have two simple equations:
1) 12.99=100%
2) x=61%
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:
12.99/x=100%/61%
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% of 12.99

12.99/x=100/61
(12.99/x)*x=(100/61)*x       - we multiply both sides of the equation by x
12.99=1.6393442622951*x       - we divide both sides of the equation by (1.6393442622951) to get x
12.99/1.6393442622951=x
7.9239=x
x=7.9239

now we have:
61% of 12.99=7.9239
