In the given number line, what fraction is marked?
a number line with -1, 0, and 1 marked; there are evenly spaced ticks, with eight ticks between -1 and 0, eight between 0 and 1, and so on; there is a dot marked at the fifth tick to the right from 0
There are subdivisions between and and the mark is at the fifth subdivision. So the mark is of the way from to and therefore represents the fraction
