Answer 1

Respuesta:

E = 9/5

Explicación paso a paso:

$( \frac{3}{4} + \frac{5}{4} ) - ( \frac{2}{5} - \frac{1}{5} ) = \\ \\ ( \frac{3 + 5}{4} ) - ( \frac{2 - 1}{5} ) = \\ \\ ( \frac{8}{4} ) - ( \frac{1}{5} ) = \\ \\ \frac{2}{1} - \frac{1}{5} = \\ \\ \frac{(2 \times 5) - (1 \times 1)}{1 \times 5} = \\ \\ \frac{10 - 1}{5} = \\ \\ \frac{9}{5}$
