Question

2) Calcule
a) 2/3+3/6
b) 5/6 - 2/6
c) 5/6 + 2/3
d) 7/8 - 1/6 ​

Answer 1

Resposta:

$\dfrac{2}{3}+\dfrac{3}{6}=\dfrac{4+3}{6}=\dfrac{7}{6}$

$\dfrac{5}{6}-\dfrac{2}{6}=\dfrac{5-2}{6}=\dfrac{3}{6}$

$\dfrac{5}{6}+\dfrac{2}{3}=\dfrac{5+4}{6}=\dfrac{9}{6}$

$\dfrac{7}{8}-\dfrac{1}{6}=\dfrac{21-4}{24}=\dfrac{17}{24}$
