c) (3/4).(−8/5). (−4/9)

d) 3/7÷ (−6/15)

e) 3/2÷ (−6/15)

Answer 1

Respuesta:

a $\left(\frac{2}{3}\right)\left(-\frac{3}{2}\right)=-1$

b $\left(\frac{4}{5}\right)\left(-\frac{10}{9}\right)=-\frac{8}{9}\quad \left(\mathrm{Decimal:\quad }\:-0.88888\dots \right)$

c $\left(\frac{3}{4}\right)\left(-\frac{8}{5}\right)\left(-\frac{4}{9}\right)=\frac{8}{15}\quad \left(\mathrm{Decimal:\quad }\:0.53333\dots \right)$

d $\frac{\frac{3}{7}}{\left(-\frac{6}{15}\right)}=-\frac{15}{14}\quad \left(\mathrm{Decimal:\quad }\:-1.07142\dots \right)$

e $\frac{\frac{3}{2}}{\left(-\frac{6}{15}\right)}=-\frac{15}{4}\quad \left(\mathrm{Decimal:\quad }\:-3.75\right)$
