1. 3 1/4 kg - 1 1/2 kg + 2 3/4 = (3-1+2) + (1/4 - 1/2 + 3/4) = 4 + (1/4 - 2/4 + 3/4) = 4 2/4 = D. 4 1/2 kg
= (3-1+2) + (1/4 - 1/2 + 3/4)
= 4 + (1/4 - 2/4 + 3/4)
= 4 2/4 = D. 4 1/2 kg
2. 0,5 × (1/2 : 1/4) × 1 1/2
= 1/2 × (1/2 × 4/1) × 3/2
= 1/2 × 2/1 × 3/2
= 3/2 = C. 1 1/2
2. 1/2 x (1/2 : 1/4) x 3/2
= 1/2 x (1/2 x 4/1) x 3/2
= 1/2 x 4/2 x 3/2
= 12/8
= 1 4/8 atau 1 1/2
