Answer 1

1)15 4/7
2)0,8
3)4 1/3
4)-13/15
5)7,2
6)-13/24(26/48)

Answer 2

$- x = 15 \frac{4}{7} \\ x = - 15 \frac{4}{7}$
$- x = - 0.8 \\ x = 0.8$
$- x = - 4 \frac{1}{3} \\ x = 4 \frac{1}{3}$
$- x = \frac{5}{6} - \frac{1}{9} \\ - x = \frac{13}{18} \\ x = - \frac{13}{18}$
5) - х= - 7,2
х= 7,2
6) - х= 3/8 + 1/6
- х= 13/24
х= - 13/24
