Question

seis oitavos + tres sextos - dois terços

Answer 1

Olá boa noite!

$\dfrac{6}{8} +\dfrac{3}{6} - \dfrac{2}{3}$

Tirando o MMC:

8,6,3|2
4,3,3|2
2,3,3|2
1,3,3|3
1,1,1 / 2×2×2×3=24

$\dfrac{18}{24} +\dfrac{12}{24} -\dfrac{16}{24}$

$\dfrac{30}{24} -\dfrac{16}{24}$

$\dfrac{14}{24}$

$\dfrac{7}{12}$
