Simplify the following:
(i) (2/1/2 + 1/5) ÷ (2/1/2 + 1/5)
(ii) (1/4 + 1/5) ÷ (1 − (3/8 × 3/5))
(i) = (2 1/2 + 1/5) ÷ (2 1/2 + 1/5)
= (5/2 + 1/5) ÷ (5/2 + 1/5)
= (25 + 2/10) ÷ (25/2)
= 27/10 × 2/25
= 27/125
(ii) = (1/4 + 1/5) ÷ (1 − (3/8 × 3/5))
= (5 + 4/20) ÷ (1 − 9/40)
= 9/20 ÷ (40 − 9/40)
= 9/20 × 40/31
= 18/31
