Answer 1

Resposta:

$a) \frac{4}{6} + \frac{2}{6} = \frac{4 + 2}{6} = \frac{6}{6} = 1$

$\frac{8}{3(7)} - \frac{5}{7(3)} = \frac{56}{21} - \frac{15}{21} = \frac{41}{21}$

$c)13.45 + 0.3 \\ \frac{1345}{100(1)} + \frac{3}{10(10)} = \frac{1345}{100} + \frac{30}{100} \\ = \frac{1345 + 30}{100} \\ = \frac{1375 \div 25}{100 \div 25} = \frac{55}{4}$

$46.86 - 34.9 = 11.96$
