Answer 1

Respuesta:

Explicación paso a paso:

$\frac{1}{5}\div \frac{3}{10}=\frac{\frac{1}{5}}{\frac{3}{10}}=\\\\=\frac{(10)(1)}{(3)(5)}=\frac{10}{15}=\frac{2}{3}\\\\\frac{1}{2}+\frac{2}{3}=\frac{(3)(1)+(2)(2)}{6}=\\\\=\frac{3+4}{6}=\frac{7}{6}\\\\\frac{2}{4}-\frac{1}{5}=\frac{1}{2}-\frac{1}{5}=\frac{5-2}{10}=\frac{3}{10}$
