Question

Cuánto es 2/5 + 3/10 + 1/20 me podrían ayudar

Answer 1

Explicación paso a paso:

$\frac{2}{5} + \frac{3}{10} + \frac{1}{20} = \frac{3}{4} \\ \\ \frac{2}{5} + \frac{3}{10} = \frac{20 + 15}{50} = \frac{35}{50} = \frac{7}{10} \\ \frac{7}{10} + \frac{1}{20} = \frac{140 + 10}{200} = \frac{150}{200} = \frac{15}{20} = \frac{3}{4}$
