Answer 1

Explicación paso a paso:

$a.( \frac{4}{7} ) - ( \frac{3}{5} ) = \\ ( \frac{20}{35} ) - ( \frac{21}{35} ) = \frac{ - 1}{35} \\ b.( \frac{5}{9} ) - ( \frac{10}{45} ) = \\ ( \frac{5}{9} ) - ( \frac{2}{9} ) = \frac{3}{9} = \frac{1}{3} \\ c.( \frac{5}{3} ) - ( - \frac{9}{23} ) = \\ ( \frac{115}{69} ) - ( - \frac{27}{69} ) = \frac{142}{69} \\ d.( - \frac{34}{13} ) - ( - \frac{24}{26} ) = \\ ( - \frac{68}{26} ) - ( - \frac{24}{26} ) = \frac{44}{26} = \frac{22}{13}$
