Question

resolva as operações com frações a 3/8 +1/8+2/8= b 4/5-2/3= c 3/4+ 1/7-1/2= d 2/6+1/9+1/4= ​

Answer 1

Explicação passo-a-passo:

A

$\dfrac{3}{8} + \dfrac{1}{8} + \dfrac{2}{8}$

$\dfrac{3 + 1 + 2}{8}$

$\dfrac{6}{8}$

$\dfrac{6 {}^{ \div 2} }{8 {}^{ \div 2} }$

$\dfrac{3}{4}$>>> resposta

B

$\dfrac{4}{5} - \dfrac{2}{3}$

$\dfrac{12 - 10}{15}$

$\dfrac{2}{15}$>>>> resposta

C

$\dfrac{3}{4} + \dfrac{1}{7} - \dfrac{1}{2}$

$\dfrac{21 + 4 - 14}{28}$

$\dfrac{11}{28}$>>>> resposta

D

$\dfrac{2}{6} + \dfrac{1}{9} + \dfrac{1}{4}$

$\dfrac{12 + 4 + 9}{36}$

$\dfrac{25}{36}$>>> resposta
