#### Question 2. What number should be added to −4/11 to get −3/8?

Required number = -3/8 – (-4/11)

= (-3/8) + (-4/11)

= (-33+32)/88

= -1/88

#### Question 4. If the product of two rational numbers is 25/42 and one of them -2(6/7), find the other.

Product of two numbers = 25/42

One number = −2(6/7) = -20/7

Then second number = 25/42 ÷ (-20/7)

#### Question 7. Find the additive inverse of the following:

(i) -13(7/8)
(ii) 4(3/6)

(i) Additive inverse of −13(7/8) = 13(7/8)
(ii) Additive inverse of 4(3/6) = 4(3/6)

#### Question 8. Find the multiplicative inverse of the following:

(i) 23/46
(ii) 0

(i) Multiplicative inverse of 23/46 is 46/-23 = -2

(ii) Multiplicative inverse of 0 is not defined.

(i) 3/11
(ii) 5/17

#### Question 11. If p = −4/9 , q = 2/3 and r = −8/11, then verily the following:

(i) p + (q + r) = (p + q) + r
(ii) p × q = q × p
(iii) p × (q + r) = p × q + p × r
(iv) (p + q) ÷ r = p ÷ r + q ÷ r.

(ii) p × q = q × p

(iv) (p + q) ÷ r = p ÷ r + q ÷ r.

LHS = RHS

#### Question 12. A wedding cake weighed 8 kg. If 2/5 th of its weight was flour, 5/16 th was sugar, 1/4 th was cream and the rest were nuts, find the weight of nuts.

Weight of a wedding cake = 8 kg

Weight of Hour in it = 2/5 th of 8 kg = 16/5 kg
