Answer 1

• • • •

$\frac{15}{12} - \frac{17}{12} = \frac{15 - 17}{12} \\ \\ \frac{ - 2}{12} = \red{\frac{ - 1}{6}}$

• • • •

$\frac{6 - 10 + 6}{12} = \frac{12 - 10}{12} \\ \\ \frac{2}{12} = \red{\frac{1}{6}}$

• • • •

$\frac{6 + 10 + 6}{12} = \frac{12 + 10}{12} \\ \\ \frac{22}{12} = \red{\frac{11}{6}}$

• • • •

$\frac{1}{2} + \frac{6}{3} = \frac{3 + 12}{6} \\ \\ \frac{16}{6} = \red{ \frac{8}{3}}$

• • • •

$\frac{7}{3} - \frac{1}{1} = \frac{7 - 3}{3} \\ \\ \red{\frac{4}{3}}$

espero ter ajudado :))
