calculos por favor.

Answer 1

Resposta:

$a)7 \times \frac{3}{6} = \frac{21}{6} = \frac{7}{2}$

$b)7 \times \frac{3}{7} = 1 \times \frac{3}{1} = 3$

$c) \frac{1}{9} \times \frac{1}{8} = \frac{1}{72}$

$d) \frac{2}{5} \times \frac{2}{4} = \frac{1}{5} \times \frac{2}{2} = \frac{2}{10} = \frac{1}{5}$

$e)10 \div \frac{2}{5} = 10 \times \frac{5}{2} = 5 \times \frac{5}{1} = 25$

$f)7 \times \frac{3}{6} = \frac{21}{6} = \frac{7}{2}$
