What is 5.31 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 5.31% of the output value, so we can write it down as x=5.31%.
5. Now we have two simple equations:
1) 7.9=100%
2) x=5.31%
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:
7.9/x=100%/5.31%
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 5.31% of 7.9

7.9/x=100/5.31
(7.9/x)*x=(100/5.31)*x       - we multiply both sides of the equation by x
7.9=18.832391713748*x       - we divide both sides of the equation by (18.832391713748) to get x
7.9/18.832391713748=x
0.41949=x
x=0.41949

now we have:
5.31% of 7.9=0.41949
