Question

calcule,simplifiquando quando possivel

Answer 1

a) $\frac{9}{20} . \frac{5}{6}$ = $\frac{45}{120} = \frac{15}{60} = \frac{3}{12} = \frac{1}{4}$

b) $\frac{4}{5} . \frac{25}{12} = \frac{1}{1} . \frac{5}{3} = \frac{5}{3}$

c) $\frac{3}{8} .\frac{5}{3} = \frac{15}{24} = \frac{5}{8}$

d) $\frac{5}{6} : \frac{2}{3} = \frac{5}{6} . \frac{3}{2} = \frac{15}{12} = \frac{5}{4}$

e) $\frac{11}{8} . \frac{4}{7} = \frac{11}{2} . \frac{1}{7} = \frac{11}{14}$

f) $4 : \frac{3}{5} = 4 . \frac{5}{3} = \frac{20}{3}$

g) $\frac{11}{4} : \frac{9}{4} = \frac{11}{4} . \frac{4}{9} = \frac{11}{9}$
