Answer 1

Explicación paso a paso:

$\frac{3}{4} - \frac{2}{5} = \frac{15 - 8}{20} = \frac{7}{20}$

$\frac{1}{4} + \frac{1}{2} = \frac{4 + 2}{8} = \frac{6}{8} = \frac{3}{4}$

$\frac{1}{3} + \frac{2}{5} = \frac{5 + 6}{15} = \frac{11}{15}$

$\frac{1}{2} + \frac{5}{10} = \frac{10 + 10}{20} = \frac{20}{20} = 1$

$\frac{1}{4} + \frac{1}{3} = \frac{3 + 4}{12} = \frac{7}{12}$

$\frac{3}{4} - \frac{1}{2} = \frac{6 - 4}{8} = \frac{2}{8} = \frac{1}{4}$

$\frac{4}{5} - \frac{1}{2} = \frac{8 - 5}{10} = \frac{3}{10}$

$\frac{3}{10} + \frac{3}{5} = \frac{15 + 30}{50} = \frac{45}{50} = \frac{9}{10}$

$\frac{1}{2} - \frac{1}{5} = \frac{5 - 2}{10} = \frac{3}{10}$

$\frac{4}{5} - \frac{1}{4} = \frac{16 - 5}{20} \frac{11}{20}$
