Answer 1

((3/2)^2-11/5*3/2)  : 7/4
(9/4-33/10)*4/7
-21/20*4/7
=-3/5

Answer 2

${1.5}^{2} = 2.25$
$2 \frac{1}{5} \times 1 \frac{1}{2} = \frac{11}{5} \times \frac{3}{2} = \frac{33}{10} = 3.3$
$2.25 - 3.3 = - 1.05$
$- 1 \frac{5}{100} \div 1 \frac{3}{4} = - 1 \frac{1}{20} \div \frac{7}{4} = \\ = - \frac{21}{20} \times \frac{4}{7} = - \frac{3}{5} = - 0.6$
