Answer 2

15/17 . 218/219  . -17/15
=15/17 .  -17/15 . 218/219

Answer 3

\(\dfrac{15}{17}.\dfrac{218}{219}.\dfrac{-17}{15}\)

= \(\dfrac{15.218.\left(-17\right)}{17.219.15}\)

= \(\dfrac{1.218.\left(-1\right)}{1.219.1}\)

= \(\dfrac{-218}{219}\)

Answer 4

\(\dfrac{15}{17}\cdot\dfrac{218}{219}\cdot\dfrac{-17}{15}=-\dfrac{218}{219}\)
