a) (100 + 67) x 67 + (200 - 33) x 33
= 167 x 67 + 167 x 33
= 167 x (67 + 33)
= 167 x 100
= 16700
b) 45,651 x 73 + 45,651 x 20 + 45,651 x 7
= 45,651 x (73 + 20 + 7)
= 45,651 x 100
= 4565,1
c) 14,2 x 30 + 14,2 x 57 + 14,2 x 13
= 14,2 x (30 + 57 + 13)
= 14,2 x 100
= 1420
a) (100 + 67) × 67 + (200 - 33) × 33
= 167 × 67 + 167 × 33
= 167 × 100
= 16700
b) 45,651 × 73 + 45,651 × 20 + 45,651 × 7
= 45,651 × (73 + 20 + 7)
= 45,651 × 100
= 4565,1
c) 14,2 × 30 + 14,2 × 57 + 14,2 × 13
= 14,2 × (30 + 57 + 13)
= 14,2 × 100
= 1420
