Jawab:
(c). 7 13/18 kg
Penjelasan dengan langkah-langkah:
total beras = 47,5 kg
2/5 bagian = 2/5 × 47,5 kg = 19 kg
sisa beras = 47,5 kg - (19 kg + 5 1/3 kg ) = 47,5 kg - 73/3 kg = 139/6 kg
misal berat beras pedagang kedua = x, maka berat beras pedagang pertama = 2x, sehingga didapat
x + 2x = 3x = 139/6 kg
⇒ x = 139/18 kg
Jadi, didapat berat beras pedagang kedua yakni
x = 139/18 kg = 7 13/18 kg
