Question

1 - Determine o resultado das fraçoes abaixo.
a) 2/3 x 3/2 =

b) 2/3 x 3/7 =

c) 5/6 : 4/5 =

d) 1/2 : 3/4 =

e) 5/6 : 8/9 =

Answer 1

$a) \: \frac{2}{3} \times \frac{3}{2} = \frac{6}{6} = 1$

$b) \: \frac{2}{3} \times \frac{3}{7} = \frac{6}{21}^{ \div 3} = \frac{2}{7}$

$c) \: \frac{5}{6} \div \frac{4}{5} = \frac{25}{24}$

$d) \: \frac{5}{6} \div \frac{8}{9} = \frac{45}{48}^{ \div 3} = \frac{15}{16}$
