96/ 30
32/10
16/5

maaf kalo salah

[tex]2 \frac{2}{5} \times 1 \frac{2}{8} \times \frac{6}{7} = \\ \frac{12}{5} \times \frac{10}{8} \times \frac{6}{7} = \frac{720}{280} = 2 \frac{160}{280} ( \div \frac{40}{40} ) = 2 \frac{4}{7} [/tex]

[tex]2 \frac{4}{6} \times \frac{4}{8} \times 2 \ \frac{2}{5} = \frac{16}{6} \times \frac{4}{8} \times \frac{12}{5} = \frac{768}{240} ( \div \frac{48}{48} ) = 3 \frac{1}{5} [/tex]
