Question

11. Efetue as adições:
a) 3/6 + 2/6 =
b) 13/7 + 1/7 =
c) 2/7+ 1/7 =
d) 4/10 + 3/10 =
e) 5/6 + 1/6 =
f) 8/6 + 6/6 =​

Answer 1

$\frac{3}{6} + \frac{2}{6} = \frac{5}{6}\\\\\frac{13}{7} + \frac{1}{7} = \frac{14}{7} = 2\\ \\\frac{2}{7} + \frac{1}{7} = \frac{3}{7} \\\\\frac{4}{10} + \frac{3}{10} = \frac{7}{10} \\\\\frac{5}{6} + \frac{1}{6} = \frac{6}{6} = 1\\\\\frac{8}{6} + \frac{6}{6} = \frac{14}{6} = \frac{7}{3}$
