What is 3.16 percent of 7.9 - 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 7.9 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 7.9 is 100%, so we can write it down as 7.9=100%.
4. We know, that x is 3.16% of the output value, so we can write it down as x=3.16%.
5. Now we have two simple equations:
1) 7.9=100%
2) x=3.16%
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:
7.9/x=100%/3.16%
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 3.16% of 7.9

7.9/x=100/3.16
(7.9/x)*x=(100/3.16)*x       - we multiply both sides of the equation by x
7.9=31.645569620253*x       - we divide both sides of the equation by (31.645569620253) to get x
7.9/31.645569620253=x
0.24964=x
x=0.24964

now we have:
3.16% of 7.9=0.24964
