Answer: 1. We assume, that the number 38.25 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 38.25 is 100%, so we can write it down as 38.25=100%.
4. We know, that x is 85% of the output value, so we can write it down as x=85%.
5. Now we have two simple equations:
1) 38.25=100%
2) x=85%
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:
38.25/x=100%/85%
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 85% of 38.25
38.25/x=100/85
(38.25/x)*x=(100/85)*x -
38.25=1.1764705882353*x -
38.25/1.1764705882353=x
32.5125=x
x=32.5125
now we have:
85% of 38.25=32.5125
