What is 2 percent of 6.8 - 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 6.8 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 6.8 is 100%, so we can write it down as 6.8=100%.
4. We know, that x is 2% of the output value, so we can write it down as x=2%.
5. Now we have two simple equations:
1) 6.8=100%
2) x=2%
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:
6.8/x=100%/2%
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 2% of 6.8

6.8/x=100/2
(6.8/x)*x=(100/2)*x       - we multiply both sides of the equation by x
6.8=50*x       - we divide both sides of the equation by (50) to get x
6.8/50=x
0.136=x
x=0.136

now we have:
2% of 6.8=0.136
