untuk menyelesaikan soal ini, kita perlu menyamakan penyebutnya:
= (2 ⅔ + 1 ¼) × ½ - 1 ⅓
= ((2 × 3 + 2)/3 + (1 × 4 + 1)/4) × ½ - 1 ⅓
= ((6 + 2)/3 + (4 + 1)/4) × ½ - 4/3
= (8/3 + 5/4) × ½ - 4/3
= ((8 × 4)/(3 × 4) + (5 × 3)/(4 × 3)) × ½ - 4/3
= (32/12 + 15/12) × ½ - 4/3
= 47/12 × ½ - 4/3
= 47/24 - (4 × 8)/(3 × 8)
= 47/24 - 32/24
= 15/24 → bagi 3
