Penjelasan dengan langkah-langkah:
[tex] \frac{1}{8} + \frac{3}{4} = \frac{1}{6} + \frac{6}{8} { \bold{ = \frac{7}{8}}} [/tex]
[tex]1 \frac{2}{5} + \frac{5}{6} = [/tex]
[tex] = \frac{42}{30} + \frac{25}{30} [/tex]
[tex] = \frac{42 + 25}{30} [/tex]
[tex] = \frac{67}{30} [/tex]
[tex]{ \bold{ = 2 \frac{7}{30}}} [/tex]
[tex] \frac{1}{3} + \frac{3}{6} + \frac{3}{4} = [/tex]
[tex] = \frac{10 + 9}{12} [/tex]
[tex] = \frac{19}{12} [/tex]
[tex]{ \bold{ = 1 \frac{7}{12}}} [/tex]
[tex]2 \frac{1}{6} + 1 \frac{4}{8} + \frac{4}{3} = [/tex]
[tex] = \frac{11 + 4}{3} [/tex]
[tex] = \frac{15}{3} [/tex]
[tex] = \frac{5 \times 3}{1 \times 3} [/tex]
[tex] = \tt \frac{5}{1} \ atau \: 5[/tex]

Penjelasan dengan langkah-langkah:
1. [tex]\frac{1}{8} + \frac{3}{4} = \frac{1}{8} + \frac{6}{8} = \frac{7}{8}[/tex]
2. [tex]1\frac{2}{5} + \frac{5}{6} = \frac{7}{5} + \frac{5}{6} = \frac{42}{30} + \frac{25}{30} = \frac{67}{30} = 2\frac{7}{30}[/tex]
3. [tex]\frac{1}{3} + \frac{3}{6} + \frac{3}{4} = \frac{4}{12} + \frac{6}{12} + \frac{9}{12} = \frac{19}{12} = 1\frac{7}{12}[/tex]
4. [tex]2\frac{1}{6} + 1\frac{4}{8} + \frac{4}{3} = \frac{13}{6} + \frac{12}{8} + \frac{4}{3} = \frac{52}{24} + \frac{36}{24} + \frac{32}{24} = \frac{120}{24} = 5[/tex]
