​

Answer 1

$\frac{2}{3} + \frac{4}{5} = \frac{10 + 12}{15} = \frac{22}{15}$

$\frac{7}{9} - \frac{1}{5} = \frac{35 - 9}{45} = \frac{26}{45}$

$\frac{5}{4} \times \frac{12}{11} = \frac{5 \times 3}{11} = \frac{15}{11}$

$\frac{11}{3} \div \frac{4}{6} = \frac{11}{3} \times \frac{6}{4} = 11 \times \frac{2}{4} = 11 \times \frac{1}{2} = \frac{11}{2}$
