Me ajudem por favor!!

Answer 1

Vamos lá.

(g)

$\frac{3}{4} - \frac{2}{3} = \frac{9 - 8}{12} = \frac{1}{12}$

(h)

$\frac{2}{5} - \frac{1}{3} = \frac{6 - 5}{15} = \frac{1}{15}$

(i)

$\frac{6}{4} - \frac{1}{7} + \frac{1}{2} = \frac{42 - 4}{28} = \frac{38}{28} + \frac{1}{2} = \frac{76 + 28}{56} = \frac{104}{56}$

(j)

$\frac{2}{9} + \frac{1}{8} - \frac{1}{6} = \frac{16 + 9}{72} = \frac{25}{72} - \frac{1}{6} = \frac{150 - 72}{432} = \frac{78}{432}$

(k)

$\frac{1}{3} + 3 = \frac{1}{3} + \frac{3}{1} = \frac{1 + 9}{3} = \frac{10}{3}$
