c;5/6.6/5
d;7/8.1/6.2/3
e;5/2.2/3.2/4

Answer 1

a;3/4.5/6= 15/24

b;4/5.3/7= 12/35

c;5/6.6/5= 30/30 = 1

d;7/8.1/6.2/3= 14/144

e;5/2.2/3.2/4=20/24

Answer 2

Oi

a) $\frac{3}{4}.\frac{5}{6}= \frac{15}{24}:3= \frac{5}{8}$

b) $\frac{4}{5}. \frac{3}{7}= \frac{12}{35}$

c) $\frac{5}{6}.\frac{6}{5}= \frac{30}{30}=1$

d)$\frac{7}{8}. \frac{1}{6}. \frac{2}{3}= \frac{14}{144}:2= \frac{7}{72}$

e) $\frac{5}{2}. \frac{2}{3}. \frac{2}{4}= \frac{20}{24}:4= \frac{5}{6}$

Espero ter ajudado.

Bons estudos.
