Answer:

please mark as brainliest

Step-by-step explanation:

(i)The rational number between 7 and 8

= (7 + 8)/2 = 15/2 = 7.5

(ii)The rational number between 3.5 and 5

= (3.5 + 5)/2 = 8.5/2 = 4.25

(iii)The rational number between 2 and 3.2

= (2 + 3.2)/2 = 5.2/2 = 2.6

(iv)The rational number between 4.2 and 3.6

= (4.2 + 3.6)/2 = 7.8/2 = 3.9

(v) The rational number between 1/2 and 2

= (1 + 2)/ (2 × 2) = 3/4 = 1.25
