pak Wahid mempunyai 75 4 per 5 kg padi dan 21 per 3 kg jagung kemudian tabloid membeli 3 31 per 4 kg kedelai berapa KG jumlah seluruhnya?? buat caranya

75 (4/5) + (21/3) + 3 (31/4)
= 379/5 + 21/3 + 43/4
= (1/60) × [(379 × 12) + (21 × 20) + (43 × 15)]
= (1/60) × (4548 + 420 + 645)
= (1/60) × 5613
= 5613/60
= 93 (33/60)
= 93 (11/20)


Semoga benar yaa
