Answer 1

1) 16.7-(-8.9)= 16.7 + 8.9= 25.6
2)7.2-8.9= -1.7
3) 0 - 5.7= - 5.7
4) -13.6 - 14.4= -28
5) -14.8-(-8.12) = -14.8 + 8.12= -6. 68
6) 0 -(-19.3) = 19.3
7) -7/24-(-17/36)= $\frac{7}{24}$ + $\frac{17}{36}$ = - $\frac{21}{72}$ + $\frac{34}{72}$ = $\frac{13}{72}$
8) 2/9-1/3= $\frac{2-3}{9}$ = - $\frac{1}{9}$
9) 3 1/5-(-4 1/7)= $\frac{16}{5}$ + $\frac{29}{7}$ = $\frac{112}{35}$ + $\frac{145}{35}$  = $\frac{157}{35}$ = 4$\frac{x}{y} \frac{17}{35}$
