Answer 1

Respuesta:

a.$\left(-\frac{2}{9}\right)\left(\frac{8}{11}\right)=-\frac{16}{99}$

b.$\left(\frac{3}{7}\right)\left(\frac{8}{5}\right)=\frac{24}{35}$

c.$\left(-\frac{3}{2}\right)\left(\frac{2}{7}\right)=-\frac{3}{7}$

d.$\left(-\frac{4}{9}\right)\left(-\frac{7}{3}\right)=\frac{28}{27}$

e.$\left(\frac{9}{15}\right)\left(-\frac{5}{9}\right)=-\frac{1}{3}\quad$

f.$\left(\frac{13}{15}\right)\left(-\frac{2}{11}\right)=-\frac{26}{165}$

g.$\left(\frac{27}{4}\right)\left(-\frac{3}{10}\right)=-\frac{81}{40}$

h.$\left(-\frac{9}{9}\right)\left(-\frac{11}{8}\right)=\frac{11}{8}$

i.$\left(-\frac{15}{11}\right)\left(+\frac{2}{7}\right)=-\frac{30}{77}\quad$

j.$\left(+\frac{1}{7}\right)\left(-\frac{25}{11}\right)=-\frac{25}{77}$

Divisiones:

a. $\frac{\left(+\frac{2}{9}\right)}{\left(-\frac{13}{16}\right)}=-\frac{32}{117}$

b.$\frac{\left(-\frac{7}{2}\right)}{\left(-\frac{1}{6}\right)}=21$

c.$\frac{\left(+\frac{7}{6}\right)}{\left(+\frac{5}{6}\right)}=\frac{7}{5}$

d.$\frac{\left(+\frac{7}{9}\right)}{\left(-\frac{10}{4}\right)}=-\frac{14}{45}\quad$

e.$\frac{\left(-\frac{2}{5}\right)}{\left(-\frac{3}{4}\right)}=\frac{8}{15}$

f.$\frac{\left(+\frac{8}{5}\right)}{\left(-\frac{13}{22}\right)}=-\frac{176}{65}$

g.$\frac{\left(-\frac{12}{5}\right)}{\left(-\frac{29}{6}\right)}=\frac{72}{145}$

h.$\frac{\left(\frac{1}{9}\right)}{\left(-\frac{3}{20}\right)}=-\frac{20}{27}\quad$

i.$\frac{\left(+\frac{3}{8}\right)}{\left(-\frac{9}{5}\right)}=-\frac{5}{24}$

j.$\frac{\left(-3\right)}{\left(-\frac{7}{10}\right)}=\frac{30}{7}$
