Answer 1

$2 times 1 frac{3}{4} = 2 times frac{7}{4} = frac{7}{2} = 3 frac{1}{2}$

$1 frac{2}{7} times ( - 14) = frac{9}{7} times ( - 14) =$

$- 18$

$- 7 frac{2}{7} div ( - 3) = - frac{51}{7} div ( - 3) =$

$- frac{51}{7} times ( - frac{1}{3} ) = frac{17}{7} = 2 frac{3}{7}$

$- 3 frac{2}{5} div 5 = - frac{17}{5} times frac{1}{5} = - frac{17}{25}$
