What is 65 percent of 139.5 - 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 139.5 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 139.5 is 100%, so we can write it down as 139.5=100%.
4. We know, that x is 65% of the output value, so we can write it down as x=65%.
5. Now we have two simple equations:
1) 139.5=100%
2) x=65%
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:
139.5/x=100%/65%
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 65% of 139.5

139.5/x=100/65
(139.5/x)*x=(100/65)*x       - we multiply both sides of the equation by x
139.5=1.5384615384615*x       - we divide both sides of the equation by (1.5384615384615) to get x
139.5/1.5384615384615=x
90.675=x
x=90.675

now we have:
65% of 139.5=90.675
