What is 9.7 percent of 680 - 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 680 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 680 is 100%, so we can write it down as 680=100%.
4. We know, that x is 9.7% of the output value, so we can write it down as x=9.7%.
5. Now we have two simple equations:
1) 680=100%
2) x=9.7%
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:
680/x=100%/9.7%
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 9.7% of 680

680/x=100/9.7
(680/x)*x=(100/9.7)*x       - we multiply both sides of the equation by x
680=10.309278350515*x       - we divide both sides of the equation by (10.309278350515) to get x
680/10.309278350515=x
65.96=x
x=65.96

now we have:
9.7% of 680=65.96
