What is 0.85 percent of 280 - 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 280 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 280 is 100%, so we can write it down as 280=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) 280=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:
280/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 280

280/x=100/0.85
(280/x)*x=(100/0.85)*x       - we multiply both sides of the equation by x
280=117.64705882353*x       - we divide both sides of the equation by (117.64705882353) to get x
280/117.64705882353=x
2.38=x
x=2.38

now we have:
0.85% of 280=2.38
