Answer 1

$1. \: ( \frac{4}{3} )( - \frac{2}{4} ) = - \frac{2}{3} \\ 2. \: ( - \frac{ 5 }{2} )( \frac{2}{7} ) = - \frac{5}{7} \\ 3. \: ( - \frac{8}{4} )( - \frac{2}{5} ) = \frac{4}{5} \\ 4. \: ( - 4)(20) = - 60 \\ 5. \: ( - 6) ( - 2)( - 3) = - 36$

$6. \: ( - 40)(20) = - 800 \\ 7. \: ( - 25)( - 4) = 100 \\ 8. \: ( \frac{1}{3})( - \frac{2}{4} ) = - \frac{1}{6 } \\ 9. \: ( - 7)( - 5) = 35 \\ 10. \: ( - 2)( - 40) = 80$

$11. \: (13)( - 6) = - 78 \\ 12. \: ( - 16)( - 4) = 64 \\ 13. \: (9)( - 3)( - 2) = 54 \\ 14.( \frac{1}{9} )( - \frac{2}{4} )( - \frac{1}{2} ) = \frac{1}{36} \\ 15. \: (25)( - 2)(4) = - 200$
