What is 0.22 percent of 320 - 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 320 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 320 is 100%, so we can write it down as 320=100%.
4. We know, that x is 0.22% of the output value, so we can write it down as x=0.22%.
5. Now we have two simple equations:
1) 320=100%
2) x=0.22%
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:
320/x=100%/0.22%
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 0.22% of 320

320/x=100/0.22
(320/x)*x=(100/0.22)*x       - we multiply both sides of the equation by x
320=454.54545454545*x       - we divide both sides of the equation by (454.54545454545) to get x
320/454.54545454545=x
0.704=x
x=0.704

now we have:
0.22% of 320=0.704
