[tex]2 \frac{4}{5} [/tex]

9. A.

[tex]1 \frac{1}{8} [/tex]

Penjelasan dengan langkah-langkah:

8.

[tex]2 \frac{1}{5} + 1.35 - \frac{3}{4} \\ = \frac{11}{5} + \frac{27}{20} - \frac{3}{4} \\ = \frac{14}{5} = 2 \frac{4}{5} [/tex]

9.

[tex]2 \frac{1}{4} \div 0.64 \times \frac{8}{25} \\ = \frac{9}{4} \div \frac{16}{25} \times \frac{8}{25} \\ = 9 \times \frac{25}{16} \times \frac{2}{25} \\ = 9 \times \frac{1}{8} = \frac{9}{8} \\ = 1 \frac{1}{8} [/tex]
