NOMOR 1.
[tex] \frac{2}{5} + \frac{1}{3} = \frac{(2 \times 3) + (1 \times 5)}{15} = \frac{6 + 5}{15} = \frac{11}{15} [/tex]
NOMOR 2.
[tex] \frac{3}{4} + \frac{2}{3} = \frac{(3 \times 3) + (2 \times 4)}{12} = \frac{9 + 8}{12} = \frac{17}{12} = 1 \frac{5}{12} [/tex]
NOMOR 3.
[tex] \frac{4}{5} + \frac{3}{4} = \frac{(4 \times 4) + (3 \times 5)}{20} = \frac{16 + 15}{20} = \frac{31}{20} = 1 \frac{11}{20} [/tex]
NOMOR 4.
[tex] \frac{5}{8} + \frac{1}{2} = \frac{(5 \times 1) + (1 \times 4)}{8} = \frac{5 + 4}{8} = \frac{9}{8} = 1 \frac{1}{8} [/tex]
NOMOR 5.
[tex] \frac{2}{5} + \frac{4}{8} = \frac{(2 \times 8) + (4 \times 5)}{40} = \frac{16 + 20}{40} = \frac{36}{40} = \frac{9}{10} [/tex]
NOMOR 6.
[tex] \frac{6}{7} + \frac{3}{4} = \frac{(6 \times 4) + (3 \times 7)}{28} = \frac{24 + 21}{28} = \frac{45}{28} = 1 \frac{17}{28} [/tex]
NOMOR 7.
[tex] \frac{4}{6} + \frac{3}{4} = \frac{(4 \times 2) + (3 \times 3)}{12} = \frac{8 + 9}{12} = \frac{17}{12} = 1 \frac{5}{12} [/tex]
NOMOR 8.
[tex] \frac{4}{5} + \frac{6}{9} = \frac{(4 \times 9) + (6 \times 5)}{45} = \frac{36 + 30}{45} = \frac{66}{45} = \frac{22}{15} = 1 \frac{7}{15} [/tex]
NOMOR 9.
[tex] \frac{6}{7} + \frac{2}{3} = \frac{(6 \times 3) + (2 \times 7)}{21} = \frac{18 + 14}{21} = \frac{32}{21} = 1 \frac{11}{21} [/tex]
NOMOR 10.
[tex] \frac{5}{6} + \frac{2}{5} = \frac{(5 \times 5) + (2 \times 6)}{30} = \frac{25 + 12}{30} = \frac{37}{30} = 1 \frac{7}{30} [/tex]
