What is 1.29 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 1.29% of the output value, so we can write it down as x=1.29%.
5. Now we have two simple equations:
1) 680=100%
2) x=1.29%
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%/1.29%
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 1.29% of 680

680/x=100/1.29
(680/x)*x=(100/1.29)*x       - we multiply both sides of the equation by x
680=77.519379844961*x       - we divide both sides of the equation by (77.519379844961) to get x
680/77.519379844961=x
8.772=x
x=8.772

now we have:
1.29% of 680=8.772
