Penjelasan dengan langkah-langkah:
1.
[tex] \frac{3}{5} + \frac{1}{3} = \\ \frac{9 + 5}{15} = \frac{14}{5} \\ = 2 \frac{4}{5} [/tex]
2.
[tex] \frac{8}{15} - \frac{2}{5} = \\ = \frac{8 - 6}{15} = \frac{2}{15} [/tex]
3.
[tex] \frac{3}{5} + \frac{1}{4} - \frac{1}{2} = \\ \frac{12 + 5}{20} = \frac{17}{20} - \frac{1}{2} = \\ \frac{17 - 10}{20} = \frac{7}{20} [/tex]
4.
[tex] \frac{2}{5} + \frac{3}{10} - \frac{2}{15} = \\ \frac{4 + 3}{10} \\ \frac{7}{10} - \frac{2}{15} = \\ \frac{21 - 4}{30} = \frac{17}{30} [/tex]
5.
[tex] \frac{7}{10} - \frac{2}{5} + \frac{1}{3} = \\ \frac{7 - 4}{10} = \frac{3}{10} + \frac{1}{3} \\ = \frac{3 + 10}{30} = \frac{13}{30} [/tex]
