ghania berbelanja ke pasar membeli beras 6 3/4 kg,membeli gula 4 4/5 kg dan tepung terigu 2 1/2 kg.berapa kg belanjaan ghania seluruhnya?

Belanja keseluruhan = beras + gula + tepung terigu
6 3/4 + 4 4/5 + 2 1/2 = 27/4 + 24/5 + 5/2 = 135/20 + 96/20 + 50/20 = 281/20 = 14 1/20 kg

Total berat barang belanjaan
= 6 3/4 + 2 1/2 + 4 4/5
= 6 3/4 + 2 2/4 + 4 4/5
= 8 5/4 + 4 4/5
= (8 + 4) + (5/4 + 4/5)
= 12 + (25/20 + 16/20)
= 12 41/20
= 14 1/20 kg
