Answer 1

Explicación paso a paso:

$\frac{2}{3} + \frac{1}{9} = (\frac{2 \times 3}{3 \times 3}) + \frac{1}{9} = \frac{6}{9} + \frac{1}{9} = \frac{7}{9}$

$\frac{2}{4} + \frac{5}{8} = ( \frac{2 \times 2}{4 \times 2}) + \frac{5}{8} = \frac{4}{8} + \frac{5}{8} = \frac{9}{8}$

$\frac{3}{5} + \frac{1}{10} = ( \frac{3 \times 2}{5 \times 2}) + \frac{1}{10} = \frac{6}{10} + \frac{1}{10} = \frac{7}{10}$

$\frac{2}{4} + \frac{2}{8} = ( \frac{2 \times 2}{4 \times 2} ) + \frac{2}{8} = \frac{4}{8} + \frac{2}{8} = \frac{6}{8}$
