c) O triplo de 6/3


d) O quadrado de 2,8​

Answer 1

a)

$\frac{2}{4} + \frac{3}{6} = \frac{6}{12} + \frac{6}{12} = \frac{12}{12} = 1$

b)

$\frac{1}{5} + \frac{2}{4} + \frac{3}{2} = \frac{4}{20} + \frac{10}{20} + \frac{30}{20} = \frac{44}{20} \div 4 = \frac{11}{5}$

c)

$\frac{6}{8} - \frac{2}{3} = \frac{18}{24} - \frac{16}{24} = \frac{2}{24} \div 2 = \frac{1}{12}$
