Вычислите: а) 4 3/4+1/6,б) 5-3 4/7,в) -4*3 4/15,г) 3 3/7:(-16),д) -4 5/11-3 7/11

а) 4 3/4 + 1/6 = 4 9/12 + 2/12 = 4 11/12;б) 5 - 3 4/7 = 4 7/7 – 3 4/7 = 1 3/7;в) – 4 * 3 4/15 = - 4 * 49/15 = - 196/15 = - 13 1/15;г) 3 3/7 : (- 16) = 24/7 : (- 16/1) = 24/7 * (- 1/16) = 3/7 * (- 1/2) = - 3/14;д) - 4 5/11 - 3 7/11 = – 7 12/11 = - 8 1/11.
