Question

Answer 1

=-3/8.-5/8.-8/9

=15/64.-8/9

=-5/24

Answer 2

\(\dfrac{1}{2}.\dfrac{-3}{4}.\dfrac{-5}{8}.\dfrac{-8}{9}\)

\(=\dfrac{3}{8}.\dfrac{5}{9}\)

\(=\dfrac{-5}{24}\)

Answer 3

\(-\dfrac{5}{24}\)

Answer 4

    \(\dfrac{1}{2}.\dfrac{-3}{4}.\dfrac{-5}{8}.\dfrac{-8}{9}\)

\(=\dfrac{1.\left(-3\right).\left(-5\right).\left(-8\right)}{2.4.8.9}\)

\(=\dfrac{-5}{24}\)
