bapak membeli 6 4/7 kg pupuk membeli lagi 2 3/8 kg pupuk dipakai bapak untuk sawah sebanyak 3 2/4 kg berapa sisa pupuk bapa

Total pupuk
= 6 4/7 kg + 2 3/8 kg
= (6 + 3) + (4/7 + 3/8)
= 9 + (32/56 + 21/56)
= 9 + 51/56
= 9 51/56 kg

Sisa pupuk
= 9 51/56 kg - 3 2/4
= (9 - 3) + (51/56 - 2/4)
= 6 + (51 - 28)/56
= 6 + 23/56
= 6 23/56 kg

[tex]6 \frac{4}{7} + 2 \frac{3}{8} - 3 \frac{2}{4} \\ = (6 + 2 - 3)( \frac{4}{7} + \frac{3}{8} - \frac{2}{4} ) \\ = 5( \frac{32 + 21 - 28}{56} ) \\ = 5 \frac{25}{56} [/tex]
