**Question 1: **Multiply the reciprocal of (7/8) by the reciprocal of (-2/21)**Solution:** ∵ Reciprocal of (7/8) is (-21/2)

∴ Reciprocal of (7/8) is (8/7)

**Question 2:** The product of two rational numbers is (-28/75). If one of the numbers is (14/25), find the other.

**Solution:** ∵ Product of two numbers = -28/75

Any one of the rational numbers = 14/25

∴ The other number

Thus, the required rational number is (-2/3)

**Question 3:** Find three rational numbers between –3 and –4.**Solution: **We have: A rational number between –3 and –4

A rational number between (–3) and -7/2

A rational number between (-7/2) and (-4)

Thus, the three rational numbers are between (–3) and (–4).

**Question 4: **Find three rational number between (1/2) and (–2)**Solution:** We have: A rational number between (1/2) and (–2)

A rational number between 1/2 and (-3/4)

A rational number between (-3/4) and (–2)

Thus, the three rational numbers are between 1/2 and (–2).
