Question

-3/4 * 12/-5 * -25/6

Answer 1

\(\dfrac{-3}{4}\cdot\dfrac{12}{-5}\cdot\dfrac{-25}{6}\)

=\(\dfrac{-12}{4}\cdot\dfrac{-25}{5}\cdot\dfrac{-12}{6}\)

=\(-3\cdot\left(-5\right)\cdot\left(-2\right)\)

=\(-30\)

Answer 2

Lời giải:

\(\frac{-3}{4}.\frac{12}{-5}.\frac{-25}{6}=-\frac{3}{4}.\frac{12}{5}.\frac{25}{6}\)

\(=-\frac{3.6.2.5.5}{2.2.5.6}=-\frac{3.5}{2}=-\frac{15}{2}\)

Answer 3

\(\dfrac{-3}{4}\cdot\dfrac{12}{-5}\cdot\dfrac{-25}{6}\)

\(=-\dfrac{3\cdot12\cdot25}{4\cdot5\cdot6}\)

\(=-\dfrac{1}{2}\cdot3\cdot5\)

\(=-\dfrac{15}{2}\)
