[tex]1. \: \: 2 \frac{5}{8} [/tex]
[tex]2. \: \: 3 \frac{4}{35} [/tex]
[tex]3. \: \: 1 \frac{9}{10} [/tex]
Penjelasan dengan langkah-langkah:
[tex]1. \: \: 2 \frac{1}{4} + \frac{3}{8} = \frac{9}{4} + \frac{3}{8} = \frac{18 + 3}{8} = \frac{21}{8} = 2 \frac{5}{8} [/tex]
[tex]2. \: \: \frac{5}{7} + 2 \frac{2}{5} = \frac{5}{7} + \frac{12}{5} = \frac{25 + 84}{35} = \frac{109}{35} = 3 \frac{4}{35} [/tex]
[tex]3. \: \: 4 \frac{2}{5} - 2 \frac{1}{2} = \frac{22}{5} - \frac{5}{2} = \frac{44 - 25}{10} = \frac{19}{10} = 1 \frac{9}{10} [/tex]
