Answer 1

Explicación paso a paso:

$( \frac{1}{3} - {(\frac{1}{3})}^{2} ) \times \frac{7}{7} \\ \\ = ( \frac{1}{3} - \frac{1}{9} ) \times 1 \\ \\ = \frac{2}{9}$

$( \frac{1}{7} + \frac{5}{7} ) \div ( \frac{1}{5} + 1) \\ \\ = \frac{6}{7} \div \frac{6}{5} \\ \\ = \frac{6}{7} \times \frac{5}{6} \\ = \frac{5}{7}$

$( {2})^{2} - \frac{5}{12} \div 1 \\ \\ = 4 - \frac{5}{12} \\ \\ = \frac{43}{12}$

$\sqrt{4} - (1 - \frac{27}{26} ) + 4 \div \frac{1}{2} \\ \\ = 2 + \frac{1}{26} + 4 \times 2 \\ \\ = 2 + \frac{1}{26} + 8 \\ \\ = \frac{52 + 1 + 208}{26} \\ \\ = \frac{261}{26} = 10 \frac{1}{26}$
