Calcule os produtos em seu caderno,simplificando quando possível:
9/20•5/6=
3/8•5/3=
3•2/5••1/3=
2 1/3•3 2/5=
1/2•2/11•3/7=
4/5•0•5/4=
6/15•5/2=
7/3•3/7= ;) :) Pfv me explique e par a amanha pfv

Answer 1

a) $\frac{9}{20} . \frac{5}{6} = \frac{9}{24} = \frac{3}{8}$


b) $\frac{3}{8} . \frac{5}{3} = \frac{1}{8} . \frac{5}{1} = \frac{5}{8}$


c) $3. \frac{2}{5} . \frac{1}{3} = \frac{6}{5} . \frac{1}{3} = \frac{2}{5}$


d) $2. \frac{1}{3} .3. \frac{2}{5} = 6. \frac{1}{3}. \frac{2}{5}= \frac{4}{5}$


e) $\frac{1}{2} . \frac{2}{11} . \frac{3}{7} = \frac{1}{11}. \frac{3}{7} = \frac{1}{77}$


f) $\frac{4}{5}.0. \frac{5}{4} = 0$

g) $\frac{6}{15} . \frac{5}{2} = \frac{3}{3}. \frac{1}{1} = \frac{3}{3} =3$

h) $\frac{7}{3} . \frac{3}{7} = \frac{1}{1} . \frac{1}{1} = 1$
