D. 31/12
Penjelasan dengan langkah-langkah:
[tex]a. \: \frac{3}{4} - \frac{2}{3} = \frac{9}{12} - \frac{8}{12} = \frac{1}{12} \\ \\ b \:. \: \frac{3}{4} - \frac{5}{7} = \frac{21}{28} - \frac{20 }{28} = \frac{1}{28} \\ \\ c. \: 2 \frac{4}{9} - \frac{7}{3} = \frac{22}{9} - \frac{7}{3} = \frac{22}{9} - \frac{21}{9} = \frac{1}{9} \\ \\ d. \: \: 3 \frac{1}{4} - \frac{2}{3} = \frac{13}{4} - \frac{2}{3} = \frac{39}{12} - \frac{8}{12} = \frac{31}{12} [/tex]
