Penjelasan dengan langkah-langkah:
[tex]1. \: \: \frac{4}{5} + \frac{6}{7} = \frac{28 + 30}{35} = \frac{58}{35} = 1 \frac{23}{35} [/tex]
[tex] 2. \: \: \frac{5}{8} + \frac{4}{10} = \frac{5 }{8} + \frac{2}{5} = \frac{25 + 16}{40} = \frac{41}{40} = 1 \frac{1}{40} \\ [/tex]
[tex]3. \: \: \frac{7}{5} + \frac{6}{5} = \frac{13}{5 } = 2 \frac{3}{5} [/tex]
[tex]4. \: \: \frac{8}{12} + \frac{10}{15} = \frac{2}{3} + \frac{2}{3} = \frac{5}{3} = 1 \frac{2}{3} [/tex]
