a) 4 1/2× 6- 3: 4 1/5= 27-3: 4 1/5= 27-5/7= 26 2/7
b) 1 1/3× (2 - 3/5: 2)= 11/3* (2- 2/10)= 11/3* 9/5= 99/15= 6 3/5

A) 4 ½ × 6 - 3 : 4 ⅕ =
9/2 × 6 - 3 : 21/5 =
54/2 - 3 × 5/21 =
27 - 15/21 =
27 - 5/7 =
26 2/7
B) 11/3 × (2 - ⅗ : 2) =
11/3 × (2 - ⅗ × ½) =
11/3 × (2 - 3/10) =
11/3 × 1 7/10 =
11/3 × 17/10 =
187/30 =
6 7/30
