1) 3целых 13/24-4целых 5/12 = - 7/8
2) - 7\8 * 4/7 = - 1/2
3) 2целых 7/12-3 целых 1/18 = -17/36
4) - 17/36 * 1целую 10/17 = - 3/4
5) - 1/2 + (-3/4) = - 5/4
6)3 целых 1/6 : (-5/4) = - 19/6 * 4/5 = - 38/15
ответ: - 2 целых 8/15
3 1/6:(3 13/24-4 5/12)*4/7+(2 7/12-3 1/18)*1 10/17
1)3 13/24-4 5/12= -21/24
2)2 7/12-3 1/18= -17/36
3)3 1/6:(-21/24)= -76/21= -3 13/21
4) -3 13/21*4/7= -304/147= -2 10/147
5) -17/36*1 10 /17= -3/4
6)-2 10/147+(-3/4)= -304/147+(-3/4)=-2 481/588
