помогите пожалуйста
- 5/11 - ( -5/11)
- 8 - ( - 1/7)
- 5/12 - ( -4 )​

Answer 1

Ответ:

-5/11 - (-5/11) = -5/11 + 5/11 = 0 ;

-8 - (-1/7) = -8 + 1/7 = -56/7 + 1/7 = -55/7 = -7 6/7 ;

-5/12 - (-4) = -5/12 + 4 = -5/12 + 48/12 = 48/12 -

Answer 2

Ответ:

$- \frac{5}{11} - ( - \frac{5}{11} ) = - \frac{5}{11} + \frac{5}{11} = 0$

$- 8 - ( - \frac{1}{7} ) = - 8 + \frac{1}{7} = \\ - 7 \frac{7}{7} + \frac{1}{7} = - 7 \frac{6}{7}$

$- \frac{5}{12} - ( - 4) = - \frac{5}{12} + 4 = \\ - \frac{5}{12} + 3 \frac{12}{12} = 3 \frac{7}{12}$
