Answer 1

$3.6 - 8.7 = - 5.1$

$16.8 - ( - 2.6) = 16.8 + 2.6 = 19.4$

$0 - 7.6 = - 7.6$

$- 17.9 - 10.1 = - 28$

$- 4.8 - ( - 14.13) = - 4.8 + 14.13 = 9.33$

$0 - ( - 16.2 ) = 16.2$

$- \frac{15}{16} - ( - \frac{9}{24} ) = - \frac{15}{16} + \frac{9}{24} = - \frac{15}{16} + \frac{3}{8} = - \frac{15}{16} + \frac{6}{16} = - \frac{9}{16}$

$\frac{7}{12} - \frac{5}{6} = \frac{7}{12} - \frac{10}{12} = - \frac{3}{12} = - \frac{1}{4} = - 0.25$

$2 \frac{1}{4} - ( - 4 \frac{1}{5} ) = 2 \frac{1}{4} + 4 \frac{1}{5} = 2.25 + 4.2 = 6.45$
