Question

calcule e simplifique o resultado se for possível.

A)1/3 + 2/3 + 4/3=
B) 1/10 + 7/10 - 3/10=
C)7/15 + 3/15 - 1/10 =
D)7/8 - 2/8 - 1/8 =
E)5/3 . 2/5 =
F)6/3 . 2/4 =
G)1/7 . 3 =

Answer 1

Resposta:

Explicação passo a passo:

$\frac{1}{3} + \frac{2}{3} +\frac{4}{3} = \frac{7}{3} \\\\\frac{1}{10} +\frac{7}{10} -\frac{3}{10} = \frac{5}{10} =\frac{1}{2} \\\\\frac{7}{15} +\frac{3}{15}-\frac{1}{10}= \frac{14+6-3}{30}=\frac{17}{30}\\\\\frac{7}{8}-\frac{2}{8}-\frac{1}{8}= \frac{4}{8}\\\\\frac{5}{3}.\frac{2}{5}=\frac{2}{3}\\\\\frac{6}{3}.\frac{2}{4}= 1\\\\\frac{1}{7}.3=\frac{3}{7}$

as passagens possuem mmc, se nao lembrar recomendo rever.

bons estudos!
