Ответ:

в) 1) -2 5/11+(-1 2/11)= -26/11+(-13/11)= -39/11= -3 6/11

2) -3 6/11-7/11= -39/11-7/11= -46/11= -4 2/11

г) 1) -(-4 1/16)-2 3/4= -(-65/16)-11/4= -(-65/16)-44/16= 109/16= 6 13/16

2) 6 13/16+1 1/8= 109/16+18/16= 127/16= 7 15/16

3 задание

1) 7 5/8-9 1/4= 61/8-37/4= 61/8-74/8= -3/8= -0.375

2) 0.035-0.04= -0.005

3) -0.375-(-0.005)= -0.37
