What is 5.25 percent of 39.99 - 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 39.99 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 39.99 is 100%, so we can write it down as 39.99=100%.
4. We know, that x is 5.25% of the output value, so we can write it down as x=5.25%.
5. Now we have two simple equations:
1) 39.99=100%
2) x=5.25%
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:
39.99/x=100%/5.25%
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 5.25% of 39.99

39.99/x=100/5.25
(39.99/x)*x=(100/5.25)*x       - we multiply both sides of the equation by x
39.99=19.047619047619*x       - we divide both sides of the equation by (19.047619047619) to get x
39.99/19.047619047619=x
2.099475=x
x=2.099475

now we have:
5.25% of 39.99=2.099475
