Question

simplifique as seguintes frações, até obter uma fração irredutivel a.15/25 b.7/14 c.84/140 d.10/400 e.11/33 f.25/40 g.36/24 h.81/99

Answer 1

$a)\frac{15}{25} ( \div 5) = \frac{3}{5}$
$b) \frac{7}{14} ( \div 7)= \frac{1}{2}$
$c) \frac{84}{140} ( \div 4) = \frac{21}{35} ( \div 7) = \frac{ 3}{5}$
$d) \frac{10}{400} ( \div 10) = \frac{1}{40}$
$e) \frac{11}{33} ( \div 11) = \frac{1}{3}$
$f) \frac{25}{40} ( \div 5) = \frac{5}{8}$
$g) \frac{36}{24} ( \div 12) = \frac{3}{2}$
$h) \frac{81}{99} ( \div 9) = \frac{9}{11}$
