6.88 is what percent of 688 - 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 688 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 100% equals 688, so we can write it down as 100%=688.
4. We know, that x% equals 6.88 of the output value, so we can write it down as x%=6.88.
5. Now we have two simple equations:
1) 100%=688
2) x%=6.88
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:
100%/x%=688/6.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.88 is what percent of 688

100%/x%=688/6.88
(100/x)*x=(688/6.88)*x       - we multiply both sides of the equation by x
100=100*x       - we divide both sides of the equation by (100) to get x
100/100=x
1=x
x=1

now we have:
6.88 is 1% of 688
