Answer 1

$a) \frac{1}{3} - 0.45 = \frac{1}{3} - \frac{9}{20} = - \frac{7}{60} = - 0.116$

$b) - 10.5 - 6 \frac{5}{6} = - \frac{21}{2} - \frac{41}{6} = - \frac{52}{3} = - 17 \frac{1}{3} = - 17.3$

$c) \frac{3}{14} \times ( - 1 \frac{5}{16} ) = - \frac{3}{2} \times \frac{3}{16} = - \frac{9}{32}$

$d)( - 4 \frac{2}{7} ) \div ( - 2.1) = \frac{30}{7} \times \frac{10}{21} = \frac{10}{7} \times \frac{10}{7} = \frac{100}{49}$

2. -4/5-27/10•(-7/3)=-4/5+9/10•7=-4/5+63/10=11/2

3. -107/60
