What is 0.31 percent of 80.66 - 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 80.66 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 80.66 is 100%, so we can write it down as 80.66=100%.
4. We know, that x is 0.31% of the output value, so we can write it down as x=0.31%.
5. Now we have two simple equations:
1) 80.66=100%
2) x=0.31%
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:
80.66/x=100%/0.31%
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 0.31% of 80.66

80.66/x=100/0.31
(80.66/x)*x=(100/0.31)*x       - we multiply both sides of the equation by x
80.66=322.58064516129*x       - we divide both sides of the equation by (322.58064516129) to get x
80.66/322.58064516129=x
0.250046=x
x=0.250046

now we have:
0.31% of 80.66=0.250046
