What is 75 percent of 80.9 - 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 80.9 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 80.9 is 100%, so we can write it down as 80.9=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) 80.9=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:
80.9/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 80.9

80.9/x=100/75
(80.9/x)*x=(100/75)*x       - we multiply both sides of the equation by x
80.9=1.3333333333333*x       - we divide both sides of the equation by (1.3333333333333) to get x
80.9/1.3333333333333=x
60.675=x
x=60.675

now we have:
75% of 80.9=60.675
