Answer 2

Answer:

29 / 70 & 57 / 140

Step-by-step explanation:

given 2/5 , 3/7

let a = 2/5 & b = 3/7

to find rational number formula = a + b /2

2/5 + 3/7 /2 = 14 + 15 /7 /2

29 /35/2 = 29/35 × 1/2

29 / 70 is first rational number

let a = 2/5 , b = 29 / 70

a + b / 2 = 2/5 + 29/70 /2

28 + 29 /70 /2 = 57 /70 /2

57 / 70 × 1 /2 = 57 / 140

57 /140 is second rational number
