Question

1)efetue as divisões ​

Answer 1

a)

(3/5)/(2/3)

=(3/5)*(3/2)

=3*3/(5*2)

=9/10=0,9

b)

(10/7)/(5/14)=(10/7)*(14/5)

=(10/5)*(14/7)

=2 *2 = 4

c)

(8/9)/2 =(8/9)/(2/1)

=(8/9)*(1/2) =8/18=4/9

d)

(2+1/9)/(3+1/6)

(18/9+1/9)/(18/6+1/6)

(19/9)/(19/6)

(19/9)*(6/19)

=(19/19)*(6/9)

=6/9

=2/3

Answer 2

$a) \frac{ \frac{3}{5} }{ \frac{2}{3} } = \frac{3}{5} \times \frac{3}{2} = \frac{3 \times 3}{5 \times 2} = \frac{9}{10} = 0.9$

$b) \frac{ \frac{10}{7} }{ \frac{5}{14} } = \frac{10}{7} \times \frac{14}{5} = \frac{140}{35} = 4$

$c) \frac{ \frac{8}{9} }{2} = \frac{8}{9} \times \frac{1}{2} = \frac{8 \times 1}{9 \times 2} = \frac{8}{18} = \div \frac{2}{2} = \frac{4}{9}$

$d) \frac{2 \: \frac{1}{9} }{3 \: \frac{1}{6} } = \frac{ \frac{19}{9} }{ \frac{19}{6} } = \frac{19}{9} \times \frac{6}{19} = \frac{114}{171} = \frac{2}{3}$
