Question

(Fração)
2/3 - 1/3=
3/7 - 4/3=
5/12 - 4/6=

Answer 1

$\frac{2}{3} - \frac{1}{3} = \frac{2 - 1}{3} = \frac{1}{3 } \\ \\ \\ \\ \frac{3}{7} - \frac{4}{3} = \frac{9 - 28}{21} = \frac{ - 19}{21} \\ \\ \\ \\ \frac{5}{12} - \frac{4}{6} = \frac{5 - 8}{12} = \frac{ - 3}{12} = \\ \\ \frac{ - 1}{4}$
