Penyelesaian:

[tex] = 1 \frac{3}{4} + 2 \frac{5}{9} \\ \\ = \frac{(1 \times 4 + 3)}{4} + \frac{(2 \times 9 + 5)}{9} \\ \\ = \frac{7}{4} + \frac{23}{9} \\ \\ = \frac{(7 \times 9) + (23 \times 4)}{4 \times 9} \\ \\ = \frac{63 + 92}{36} \\ \\ = \red{\frac{155}{36} }[/tex]

[tex]=5 \frac{7}{8} + 3 \frac{5}{6} \\ \\ = \frac{5×8+7}{8} + \frac{3×6+5}{6} \\ \\ = \frac{47}{8} + \frac{23}{6} \\ \\ = \frac{(47×6)+(23×8)}{8×6} \\ \\ = \frac{282+184}{48} \\ \\ = {\frac{466÷2}{48÷2}} \\ \\ = \red{ \frac{233}{24}}[/tex]
