Answer 2

Resposta:

Explicação passo-a-passo:

1)

a) $\frac{16}{24}=\frac{16/4}{24/4}=\frac{4}{6}=\frac{4/2}{6/2}=\frac{2}{3}$

b} $\frac{20}{25}=\frac{20/5}{25/5}=\frac{4}{5}$

c) $\frac{27}{81}=\frac{27/3}{81/3}=\frac{9}{27}=\frac{9/3}{27/3}=\frac{3}{9}=\frac{3/3}{9/3}=\frac{1}{3}$

d) $\frac{14}{28}=\frac{14/2}{28/2}=\frac{7}{14}=\frac{7/7}{17/7}=\frac{1}{2}$

e) $\frac{18}{24}=\frac{18/2}{24/2}=\frac{9}{12}=\frac{9/3}{12/3}=\frac{3}{4}$

f) $\frac{24}{36}=\frac{24/6}{36/6}=\frac{4}{6}=\frac{4/2}{6/2}=\frac{2}{3}$

g) $\frac{7}{21}=\frac{7/7}{21/7}=\frac{1}{3}$

h) $\frac{12}{15}=\frac{12/3}{15/3}=\frac{4}{5}$

i) $\frac{15}{40}=\frac{15/5}{40/5}=\frac{3}{8}$

j) $\frac{8}{18}=\frac{8/2}{18/2}=\frac{4}{9}$

k) $\frac{9}{12}=\frac{9/3}{12/3}=\frac{3}{4}$

2) Frações irredutiveis:

$\frac{1}{4}$, $\frac{1}{2}$, $\frac{2}{3}$, $\frac{3}{4}$, $\frac{2}{7}$ e $\frac{5}{14}$
