What is 10.75 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 10.75% of the output value, so we can write it down as x=10.75%.
5. Now we have two simple equations:
1) 39.99=100%
2) x=10.75%
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%/10.75%
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 10.75% of 39.99

39.99/x=100/10.75
(39.99/x)*x=(100/10.75)*x       - we multiply both sides of the equation by x
39.99=9.3023255813953*x       - we divide both sides of the equation by (9.3023255813953) to get x
39.99/9.3023255813953=x
4.298925=x
x=4.298925

now we have:
10.75% of 39.99=4.298925
