Jawab:
= 2 7/9
Penjelasan :
2 2/3 × 1 1/4 : 1 1/5
= (2 + 2/3) × (1 + 1/4) : (1 + 1/5)
= (6/3 + 2/3) × (4/4 + 1/4) : (5/5 + 1/5)
= (8/3) × (5/4) : (6/5)
= (8/3) × (5/4) × (5/6)
= (8/4) × (5/3) × (5/6)
= 2 × (5/3) × (5/6)
= (2/6) × (5/3) × 5
= (1/3) × (5/3) × 5
= 25/9
= (18+7)/9
= (18/9) + (7/9)
= 2 + 7/9
= 2 7/9
