Question

calcule o valor das expressões numéricas ​

Answer 1

Resposta:

Explicação passo a passo:

$a)$

$\frac{1}{2}+\frac{5}{6}=\frac{3}{6}+\frac{5}{6}=\frac{8}{6}=\frac{4}{3}$

$b)$

$\frac{3}{4}-\frac{1}{2}=\frac{3}{4}-\frac{2}{4}=\frac{1}{4}$

$c)$

$\frac{5}{6}-\frac{1}{3}=\frac{5}{6}-\frac{2}{6}=\frac{3}{6}=\frac{1}{2}$

$d)$

$\frac{1}{3}+\frac{5}{6}=\frac{2}{6}+\frac{5}{6}=\frac{7}{6}$

$e)$

$\frac{2}{5}-\frac{3}{10} =\frac{4}{10}-\frac{3}{10}=\frac{1}{10}$

$f)$

$\frac{1}{3}-\frac{1}{6}=\frac{2}{6}-\frac{1}{6}=\frac{1}{6}$
