Note that the point A lies between the numbers 1 and 2, which indicates that the whole number part of the fraction is 1. Also note that the segment between 1 and 2 is divided into 8 equal parts, and A lies on the 4th part, which implies that the fractional part is 48. Thus, the point A corresponds to the mixed fraction 148, and 148=(8×1)+48=128=32.
Similarly, B lies between 2 and 3, with fractional part 58, and thus represents the mixed fraction 258.
Now, C lies between 0 and 1, and thus is a proper fraction.
Note that C=28=14.
