Best answer

(i) 

23 x 72 + 77 x 72

= 72(23 + 77)

= 72 x 100 = 7200

(ii) 

56 x 25 – 25 × 39 – 25 x 17

25(56 – 39 – 17)

= 25 x (56 – 56)

= 25 x 0 = 0

(iii)

27 x 47 + 55 x 8 + 27 x 53 + 45 x 8

= 27 x 47 + 27 x 53 + 55 x 8 + 45 × 8

= 27 x (47 + 53) + 8(55 + 45)

= 27 x 100 + 8 x 100

= 2700 + 800 = 3500
