What is 75 percent of 6.39 - 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 6.39 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 6.39 is 100%, so we can write it down as 6.39=100%.
4. We know, that x is 75% of the output value, so we can write it down as x=75%.
5. Now we have two simple equations:
1) 6.39=100%
2) x=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:
6.39/x=100%/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 75% of 6.39

6.39/x=100/75
(6.39/x)*x=(100/75)*x       - we multiply both sides of the equation by x
6.39=1.3333333333333*x       - we divide both sides of the equation by (1.3333333333333) to get x
6.39/1.3333333333333=x
4.7925=x
x=4.7925

now we have:
75% of 6.39=4.7925
