7/2×2/6=

5/6÷2/3=

Answer 1

Explicação passo-a-passo:

a)

$\sf \dfrac{3}{6}+\dfrac{5}{3}=\dfrac{3+10}{6}=\red{\dfrac{13}{6}}$

b)

$\sf \dfrac{2}{6}-\dfrac{5}{8}=\dfrac{8-15}{24}=\red{\dfrac{-7}{24}}$

c)

$\sf \dfrac{7}{\not{2}}\cdot\dfrac{\not{2}}{6}=\red{\dfrac{7}{6}}$

d)

$\sf \dfrac{5}{6}\div\dfrac{2}{3}$

$\sf =\dfrac{5}{6}\cdot\dfrac{3}{2}$

$\sf =\dfrac{15}{12}$

$\sf =\dfrac{15\div3}{12\div3}$

$\sf =\red{\dfrac{5}{4}}$

Explicação passo-a-passo:

$\sf \dfrac{3}{6} + \dfrac{5}{3} = \dfrac{3 + 10}{6} = \dfrac{13}{6}$

$\sf \dfrac{2}{6} - \dfrac{5}{8} = \dfrac{16 - 30}{48} = -\dfrac{14}{48} = -\dfrac{7}{24}$

$\sf \dfrac{7}{2} \times \dfrac{2}{6} = \dfrac{14}{12} = \dfrac{7}{6}$

$\sf \dfrac{5}{6} \div \dfrac{2}{3} = \sf \dfrac{5}{6} \times \dfrac{3}{2} = \dfrac{15}{12} = \dfrac{5}{4}$
