Answer 2

Explicación paso a paso:

Calcula y simplifica:

a)

$\frac{3}{7}\times 14=\frac{3 \times 14}{7}=\frac{42}{7} =6$

b)

$\frac{5}{5}\div 4 = \frac{5}{5}\times \frac{1}{4} = \frac{5 \times 1}{5 \times 4} = \frac{5}{20} = \frac{1}{4}$

c)

$\frac{7}{2}\times \frac{4}{-7}=\frac{7 \times 4}{2 \times -7}=\frac{28}{-14} =-2$

d)

$\frac{3}{11}\div \frac{-5}{11} = \frac{3}{11}\times \frac{11}{-5} = \frac{3 \times 11}{11 \times -5} = \frac{33}{-55} = \frac{-3}{5}$

e)

$\frac{2}{3}\times \frac{9}{20}=\frac{2 \times 9}{3 \times 20}=\frac{18}{60} =\frac{3}{10}$

f)

$\frac{4}{15}\div \frac{2}{5} = \frac{4}{15}\times \frac{5}{2} = \frac{4 \times 5}{15 \times 2} = \frac{20}{30} = \frac{2}{3}$

g)

$\frac{6}{35}\times \frac{-77}{36}=\frac{6 \times -77}{35 \times 36}=\frac{-462}{1260} =\frac{-11}{30}$

h)

$\frac{-48}{55}\div \frac{12}{11} = \frac{-48}{55}\times \frac{11}{12} = \frac{-48 \times 11}{55 \times 12} = \frac{-528}{660} = \frac{-4}{5}$

i)

$\frac{-3}{8}\div \frac{28}{-9} = \frac{-3}{8}\times \frac{-9}{28} = \frac{-3 \times -9}{8 \times 28} = \frac{27}{224}$
