Me ajudem por favor se puderem colocar com cálculo eu agradeço

Answer 1

Resposta:

a) 7

b) 4

c) 10

Explicação passo a passo:

a) 8/6+2/6-3/6

(corte os 6)

8+2-3

10-3

7

b) 5/20+2/20-3/20

(corte os 20)

5+2-3

7-3

4

c) 4/22+6/22

(corte os 22)

4+6

10

Answer 2

Resposta:

$A)\\ \\ \frac{8}{6} +\frac{2}{6} -\frac{3}{6} =\\ \\ mmc=6\\ \\ \frac{8+2-3}{6} =\frac{7}{6} \\ \\ B)\\ \\ \frac{5}{20}+ \frac{2}{20} -\frac{3}{20} =\\ \\ mmc=20\\ \\ \frac{5+2-3}{20} =\frac{4}{20} =simplificando~~\frac{4:4}{20:4} =\frac{1}{5} \\ \\ C)\\ \\ \frac{4}{22}+ \frac{6}{22} =\\ \\ mmc=22\\ \\ \frac{4+6}{22} =\frac{10}{22} ~~simplificando~~\frac{10:2}{22:2} =\frac{5}{11}$
