Answer:
∵ The sum of two rational numbers = -2/3
And, one of the numbers = -8/15
∴ The other rational numbers
= (-2/3) – (-8/15)
∴ LCM of 3 and 15 = 15
= (-2 × 5)/(3 × 5) + (8 × 1)/(15 × 1)
(∵ LCM of 3 and 15 = 15)
= (-10 + 8)/15 = -2/15

Answer:
let the 2nd no. be x.
x + 2/15 = 4/5
=> x = 4/5 - 2/15
=> x = 12-2/15
=> x = 10/15
=> x = 2/3
let the 2nd no. be x.
x × 3/7 = -2/3
=> x = -2/3 ÷ 3/7
=> x = -2/3 × 7/3
=> x = -14/9
