Question

oi alguém pode me ajudar ​

Answer 1

Resposta:

$a) \frac{48( \div 4)}{100( \div 4)} = \frac{12}{25} \\ \\ b) \frac{15( \div 5)}{25( \div 5)} = \frac{3}{5}$

$c) \frac{25 ( \div 25)}{150( \div 25)} = \frac{1}{6} \\ \\ d) \frac{27( \div 27)}{243( \div 27)} = \frac{1}{9}$

$e) \frac{36( \div 12)}{60( \div 12)} = \frac{3}{5} \\ \\ f) \frac{105( \div 3)}{63(\div 3)} = \frac{35( \div 7)}{21( \div 7)} = \frac{5}{3}$

$g) \frac{144( \div 12)}{36( \div 12)} = \frac{12}{3} = 4 \\ \\ h) \frac{300}{270} = \frac{30( \div 3)}{27( \div 3)} = \frac{10}{9}$

$i) \frac{225( \div 25)}{125( \div 25)} = \frac{9}{5} \\ \\ j) \frac{62( \div 2)}{124( \div 2)} = \frac{31( \div 31)}{62(31)} = \frac{1}{2}$
