Answer 1

represente a fração com o mínimo múltiplo comum dos denominadores.

$\frac{6 \times 3}{7 \times 3} + \frac{1}{3}$

$\frac{6 \times 3}{7 \times 3} + \frac{1 \times 7}{3 \times 7}$

$\frac{6 \times 3}{7 \times 3} + \frac{7}{3 \times 7}$

$\frac{18}{7 \times 3} + \frac{7}{3 \times 7}$

$\frac{18}{21} + \frac{7}{3 \times 7}$

$\frac{18}{21} + \frac{7}{21}$

$\frac{25}{21}$
