Tolong jawab kak! Makasih;)

Operasi Pecahan Campuran

[tex]m = \frac{3}{5} \times \frac{5}{8} \\ \\ = \frac{15}{40} \\ \\ = \frac{3}{8} \\ \\ n = \frac{5}{12} \div 1 \frac{3}{4} \\ \\ = \frac{5}{12} \div \frac{7}{4} \\ \\ = \frac{5}{12} \times \frac{4}{7} \\ \\ = \frac{20}{84} \\ \\ = \frac{5}{21} \\ \\ m \times n = \frac{3}{8} \times \frac{5}{21} \\ \\ = \frac{1}{8} \times \frac{5}{7} \\ \\ = \frac{5}{56} [/tex]

Jadi jawabannya yang D.

*semoga membantu. sukses selalu ^_^

[tex]m = \frac{3}{5} \times \frac{5}{8} \\ m = \frac{3}{8} [/tex]
[tex]n = \frac{5}{12} \div 1 \frac{3}{4} \\ n = \frac{5}{12} \div \frac{7}{4} \\ n = \frac{5}{12} \times \frac{4}{7} \\ n = \frac{5}{21} [/tex]
[tex]m \times n \\ = \frac{3}{8} \times \frac{5}{21} \\ = \frac{5}{56} [/tex]
semoga membantu........
