Bu Karina membeli 2 1/5 kg tepung, Bu Rini membeli 3 1/2 kg dan Bu Rahma 4 1/4 kg. Hitunglah jumlah semua tepung yang dibeli oleh Bu Karina, Bu Rini, dan Bu Rah

[tex]2 \frac{1}{5} + 3 \frac{1}{2} + 4 \frac{1}{4} \\ = (2 + 3 + 4) + ( \frac{1}{5} + \frac{1}{2} + \frac{1}{4} ) \\ = (9) + ( \frac{4 + 10 + 5}{20} ) \\ = (9) + \frac{19}{20} = 9 \frac{19}{20} [/tex]

2 1/5 + 3 1/2 + 4 1/4
= (2+3+4) + (1/5+1/2+1/4)
= (5+4) + (4/20+10/20+5/20)
= 9 + 19/20
= 9 19/20
