gente eu preciso disso pra meio q agr me ajudem pfv​

Answer 1

Explicação passo-a-passo:

a) $5.\frac{2}{3}=\frac{10}{3}$

b) $\frac{3}{4}.8=\frac{24}{4}=6$

c) $2.\frac{5}{8}=\frac{10}{8}=\frac{5}{4}$

d) $10.\frac{1}{2}=\frac{10}{2}=5$

e) $\frac{1}{7}.\frac{14}{5}=\frac{14}{35}=\frac{2}{5}$

f) $\frac{5}{12}.\frac{24}{20}=\frac{120}{240}=\frac{1}{2}$

g) $\frac{3}{4}.\frac{8}{9}.\frac{5}{2}=\frac{120}{72}=\frac{5}{3}$

h) $3\frac{1}{3}.4.\frac{2}{5}=\frac{10}{3}.4.\frac{2}{5}=\frac{80}{15}=\frac{16}{3}$

i) $\frac{7}{8}.\frac{6}{10}.\frac{8}{6}.\frac{10}{7}=\frac{3360}{3360}=1$

j) $7\frac{2}{4}.3\frac{1}{5}.2\frac{1}{3}.\frac{2}{16}.\frac{1}{30}=\frac{30}{4}.\frac{16}{5}.\frac{7}{3}.\frac{2}{16}.\frac{1}{30}=$$\frac{6720}{28800}=\frac{7}{30}$
