a) Komoditas paling banyak adalah beras

b) Komoditas paling sedikit adalah jagung

c) Beras, gandum, ketela pohon, jagung

d) Jagung, ketela pohon, gandum, beras

Nomor 3

[tex]2 \frac{1}{8} + 3 \frac{1}{2} = (2 + 3) + ( \frac{1}{8} + \frac{1}{2} ) = 5 + ( \frac{1}{8} + \frac{1 \times 4}{8} )= 5 +( \frac{1}{8} + \frac{4}{8} ) = 5 + \frac{5}{8} = 5 \frac{5}{8} \: kg[/tex]

Nomor 4

[tex]9 \frac{2}{5} - 3 \frac{3}{10} = \frac{9 \times 5 + 2}{5} - \frac{3 \times 10 + 3}{10} = \frac{47}{5} - \frac{33}{10} = \frac{47 \times 2}{10} - \frac{33}{10} = \frac{94}{10 } - \frac{33}{10} = \frac{61}{10} = 6 \frac{1}{10} \: km[/tex]

Nomor 5

[tex]12 \frac{4}{5} - 5 \frac{3}{4} - 4 \frac{1}{2} = \frac{12 \times 5 + 4}{5} - \frac{5 \times 4 + 3}{4} - \frac{4 \times 2 + 1}{2} = \frac{64}{5} - \frac{23}{4} - \frac{9}{2} = \frac{256}{20} - \frac{115}{20} - \frac{90}{20} = \frac{51}{20} = 2 \frac{11}{20} \: m[/tex]
