What is 0.3185 percent of 7 - 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 7 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 7 is 100%, so we can write it down as 7=100%.
4. We know, that x is 0.3185% of the output value, so we can write it down as x=0.3185%.
5. Now we have two simple equations:
1) 7=100%
2) x=0.3185%
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:
7/x=100%/0.3185%
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 0.3185% of 7

7/x=100/0.3185
(7/x)*x=(100/0.3185)*x       - we multiply both sides of the equation by x
7=313.97174254317*x       - we divide both sides of the equation by (313.97174254317) to get x
7/313.97174254317=x
0.022295=x
x=0.022295

now we have:
0.3185% of 7=0.022295
