Question

Efetue as multiplicações.
a)1/2x5/8=
b)7/5x2/3=
c) 1/5 x 3/4x5/3=
d) 5/4x1/3x4/7=

Answer 1

A-$\frac{1}{2} * \frac{5}{8} = \frac{5}{16}$
B-$\frac{7}{5} * \frac{2}{3} = \frac{14}{15}$
C-$\frac{1}{5} * \frac{3}{4} * \frac{5}{3} = \frac{1}{5} * \frac{1}{4} * 5 = \frac{1}{4}$
D-$\frac{5}{4} * \frac{1}{3} * \frac{4}{7} = 5 * \frac{1}{3} * \frac{1}{7} = \frac{5}{21}$
