You can do this two ways. You could plot the points on a number line and count the distance. Or you could do it like this:
You could subtract the fractions by each other by first making the numbers into decimals. Which would be .66 and .41 and subtract them. Which would be .25. Changing that into a fraction would be 1/4 So the Answer would be 1/4 is the distance between them.
Another way is to find the common denominator 2/3-5/12
8/12-5/12=3/12=
So you would count the up to that number but 2/3 would be 8/3 and you would plot it like that
