Answer 1

Resposta:

$a) \: \frac{4 \div 4}{8 \div 4} \\ \\ \frac{1}{2}$

$b) \: \frac{72 \div 72}{144 \div 72} \\ \\ = \frac{1}{2}$

$c) \: \frac{35 \div 5}{80 \div 5} \\ \\ = \frac{7}{16}$

$d) \: \frac{21 \div 7}{35 \div 7} \\ \\ = \frac{3}{5}$

$e) \: \frac{3 \div 3}{15 \div 3} \\ \\ = \frac{1}{5}$

$f) \: \frac{45 \div 9}{63 \div 9} \\ \\ = \frac{5}{7}$

$g) \: \frac{54 \div 18}{90 \div 18} \\ \\ = \frac{3}{5}$

$h) \: \frac{250 \div 50}{850 \div 50} \\ \\ = \frac{5}{17}$

$i) \: \frac{18 \div 6}{24 \div 6} \\ \\ = \frac{3}{4}$

$j) \: \frac{144 \div 16}{1024 \div 16} \\ \\ \frac{9}{64}$

$k) \: \frac{8 \div 4}{4 \div 4} \\ \\ = 2$

$l) \: \frac{16 \div 16}{48 \div 16} \\ \\ = \frac{1}{3}$

$m) \: \frac{24 \div 6}{18 \div 6} \\ \\ = \frac{4}{3}$
