$d( \frac{11}{3} + \frac{8}{3} - \frac{7}{3}) \times \frac{3}{7} =$
$c( \frac{3}{5} \times \frac{15}{9} ) + ( \frac{7}{5} \div \frac{21}{25} ) =$
​

Answer 1

Respuesta:

a.

$\frac{10}{4}$ ÷ $\frac{3-2}{6}$ = $\frac{5}{2}.\frac{6}{1}$ = 5.3 = 15

b.

$\frac{12}{3}.\frac{3}{7}=\frac{12}{7}$

c.

$\frac{3.3}{9}+(\frac{7}{5}.\frac{25}{21})= 1+\frac{5}{3} =\frac{8}{3}$
