What is 29.9 percent of 39 - 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 39 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 39 is 100%, so we can write it down as 39=100%.
4. We know, that x is 29.9% of the output value, so we can write it down as x=29.9%.
5. Now we have two simple equations:
1) 39=100%
2) x=29.9%
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:
39/x=100%/29.9%
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 29.9% of 39

39/x=100/29.9
(39/x)*x=(100/29.9)*x       - we multiply both sides of the equation by x
39=3.3444816053512*x       - we divide both sides of the equation by (3.3444816053512) to get x
39/3.3444816053512=x
11.661=x
x=11.661

now we have:
29.9% of 39=11.661
