What is 0.85 percent of 81720 - 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 81720 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 81720 is 100%, so we can write it down as 81720=100%.
4. We know, that x is 0.85% of the output value, so we can write it down as x=0.85%.
5. Now we have two simple equations:
1) 81720=100%
2) x=0.85%
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:
81720/x=100%/0.85%
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 0.85% of 81720

81720/x=100/0.85
(81720/x)*x=(100/0.85)*x       - we multiply both sides of the equation by x
81720=117.64705882353*x       - we divide both sides of the equation by (117.64705882353) to get x
81720/117.64705882353=x
694.62=x
x=694.62

now we have:
0.85% of 81720=694.62
