restas
2/5-3/10=
3/5-1/10=
1/3-2/9=​

Answer 1

Explicación paso a paso:

$sumas \\ \\ \frac{1}{3} + \frac{5}{9} = \frac{9 + 15}{18} = \frac{24}{18} = \frac{4}{3} \\ \\ \\ \frac{1}{2} + \frac{1}{4} = \frac{4 + 2}{8} = \frac{6}{8} = \frac{3}{4 } \\ \\ \\ \frac{2}{5} + \frac{1}{10} = \frac{20 + 5}{50} = \frac{25}{50} = \frac{1}{2} \\ \\ restas \\ \\ \frac{2}{5} - \frac{3}{10} = \frac{20 - 15}{50} = \frac{5}{50} = \frac{1}{10} \\ \\ \\ \frac{3}{5} - \frac{1}{10} = \frac{30 - 5}{50} = \frac{25}{50} = \frac{1}{2} \\ \\ \\ \frac{1}{3} - \frac{2}{9} = \frac{9 - 6}{27} = \frac{3}{27} = \frac{1}{9}$
