Answer 2

The total number of these rational numbers is same as the number of integers between -40 and 70, i.e., 70 - (-40) - 1 = 70 + 40 - 1 = 110 - 1 = 109. Similarly, by re-writing -4/7 and 2/7 as -400/700 and 200/700, we can insert 700 - (-400) - 1 = 700 + 400 - 1 = 1100 - 1 = 1099 rational numbers between -4/7 and 2/7.
