Adım adım açıklama:
[tex]a. \: \: 1 \frac{4}{9} + \frac{3}{9} = 1 \frac{7}{9} [/tex]
[tex]b. \: \: 3 \frac{1}{5} + \frac{8}{5} = 3 \frac{1}{5} + 1\frac{3}{5} = 4 \frac{4}{5} [/tex]
[tex]c. \: \: 1 \frac{2}{5} - \frac{3}{5} = \frac{7}{5} - \frac{3}{5} = \frac{4}{5} [/tex]
[tex]d. \: \: 2 \frac{3}{7} - \frac{5}{7} = \frac{17}{7} - \frac{5}{7} = \frac{12}{7} [/tex]
[tex]e. \: 2 + 1 \frac{4}{9} = 3 \frac{4}{9} [/tex]
[tex]f. \: \: 3 - 2 \frac{1}{4} = = \frac{12}{4} - \frac{9}{4} = \frac{3}{4} [/tex]
[tex]g. \: \: 1 \frac{4}{15} + 2 \frac{1}{15} = 3\frac{5}{15} = 3 \frac{1}{3} [/tex]
[tex]h. \: \: 3 \frac{4}{5} + 1 \frac{3}{5} =4 \frac{7}{5} = 5 \frac{2}{5} [/tex]
[tex]ı. \: \: 3 \frac{1}{6} - 2 \frac{5}{6} = \frac{19}{6} - \frac{17}{6} = \frac{2}{6} = \frac{1}{3} [/tex]
[tex]j. \: \: 2 \frac{3}{10} - 1 \frac{2}{10} = 1 \frac{1}{10} [/tex]
