Answer 1

Respuesta:

c)  - 2660/161 ≈ - 16.52

d) - 48588/4200 ≈ - 11.56

Explicación paso a paso:

$(\frac{15}{2} - \frac{5}{2} - \frac{20}{2}) / (\frac{8}{7} - \frac{9}{5} ) * (\frac{4}{7} - \frac{16}{5} + \frac{24}{5} )$

= (-10/2) ÷ (-23/35) * (76/35)

= (-175/23) * (76/35)

= - 13300/805 = - 2660/161 ≈ -16.52

$4[ \frac{3}{5} ( \frac{4}{7} - \frac{3}{5} ) -( \frac{5}{4} + \frac{2}{3}) \frac{3}{2} ]$

= 4 {(3/5) * ( -1/35) - (23/12)*(3/2)}

= 4{ -3/175 - 69/24 }

= 4 { - 12147/4200 }

= - 48588/4200 ≈ -11.56
