a,(+6/5)×(+2/9)=
b,(+1/3)×(-11/8)=
c,(+2/7)×(-1/5)×(-5/2)=
mim ajuda por favor está atividade vali pontos​

Answer 1

a)

$( + \frac{6}{5} ) \times ( + \frac{2}{9} ) = \frac{6 \times 2}{5 \times 9} = \frac{12}{45} = \frac{4}{15}$

b)

$( + \frac{1}{3} ) \times ( \frac{-11}{8} ) = \frac{1 \times ( - 11)}{3 \times 8} = \frac{ - 11}{24}$

c)

$( + \frac{2}{7} ) \times ( \frac{ - 1}{5} ) \times ( \frac{ - 5}{2} ) = \frac{2 \times ( - 1) \times ( - 5)}{7 \times 5 \times 2} = \frac{10}{70} = \frac{1}{7}$

Answer 2

a,(+6/5)×(+2/9)= 0.2666666667

b,(+1/3)×(-11/8)= .0.4583333333

c,(+2/7)×(-1/5)×(-5/2)= 0.028
