Me ajudem por favor

Answer 1

a) $\frac{3}{8}$ * $\frac{5}{3}$ = $\frac{15}{24}$ / 3 → $\frac{5}{8}$

b) 3 * $\frac{2}{5}$ * $\frac{1}{3}$ → $\frac{3}{1}$ * $\frac{2}{5}$ * $\frac{1}{3}$ = $\frac{6}{15}$ /3 → $\frac{2}{5}$

c) $\frac{1}{2}$ * $\frac{2}{11}$ * $\frac{3}{7}$ = $\frac{6}{154}$ /2 → $\frac{3}{77}$

d) $\frac{1}{2}$ * $\frac{2}{11}$ * $\frac{3}{7}$ = $\frac{6}{154}$ /2 → $\frac{3}{77}$

e) $\frac{4}{5}$ * 0 * $\frac{5}{4}$ = 0
