Q.7 find :
(a) 1/2 of (i) \(2\frac{3}{4} (ii) 4\frac{2}{9} \)
(b) 5/8 of (i) \(3\frac{5}{6} (ii) 9\frac{2}{3} \)

(a)(i) \(1/2× 2\frac{3}{4} = 1/2×11/4= 11/8=1\frac{3}{8} \)
(ii) \(1/2× 4\frac{2}{9}= 1/2 ×38/9 =38/18=19/9=2\frac{1}{9} \)
(b) (i) \(5/8 × \frac{5}{6} = 5/8×23/6=115/48 =2\frac{19}{48} \)
(ii) \(\frac{5}{8}×9\frac{2}{3}= 5/8×29/3=145/24=6\frac{1}{24} \)
