What is 6.78 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 6.78% of the output value, so we can write it down as x=6.78%.
5. Now we have two simple equations:
1) 7=100%
2) x=6.78%
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%/6.78%
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 6.78% of 7

7/x=100/6.78
(7/x)*x=(100/6.78)*x       - we multiply both sides of the equation by x
7=14.749262536873*x       - we divide both sides of the equation by (14.749262536873) to get x
7/14.749262536873=x
0.4746=x
x=0.4746

now we have:
6.78% of 7=0.4746
