a) 1/3 + 1/5 =
b) 3/4 + 1/2 =
c) 2/4 + 2/3 =
d) 2/5 + 3/10 =
e) 5/3 + 1/6 =​

Answer 1

Explicação passo-a-passo:

$a)\frac{1}{3}+\frac{1}{5}=\frac{5+3}{15}=\frac{8}{15}$

$b)\frac{3}{4}+\frac{1}{2}=\frac{3+2}{4}=\frac{5}{4}$

$c)\frac{2}{4}+\frac{2}{3} =\frac{2.3+2.4}{12}=\frac{6+8}{12}=\frac{14}{12} =\frac{7}{6}$

$d)\frac{2}{5}+\frac{3}{10}=\frac{2.2+3}{10}=\frac{4+3}{10}=\frac{7}{10}$

$e)\frac{5}{3}+\frac{1}{6}=\frac{5.2+1}{6}=\frac{10+1}{6}=\frac{11}{6}$
