Answer 1

(2 13/48 - (-2 5/12) ) : (-3 3/4) + 9 3/4 : (-13) = -2
1) 2 13/48 -(-2 5/12)= 109/48 + 29/12 = 109/48 + 116/48 = 225/48 = 75/16
2) 75/16 : (-3 3/4) = 75/16 * (-4/15) =  -5/4
3) 9 3/4 : (-13) = 39/4 * (-1/13) = -3/4
4) -5/4 + (-3/4) = -5/4 - 3/4 = -8/4 = -2

(1 2/3 -3,6) : (-2 7/9 + 4 1/15) * (-2,6) = 3,9
1) 1 2/3 - 3 6/10 = 5/3 - 36/10 = 50/30 - 108/30 = -58/30 = -29/15
2) -2 7/9 + 4 1/15 = -25/9 + 61/15 = -125/45 + 183/45 = 58/45
3) -29/15 : (58/45) = -29/15 * (45/58) = -3/2
4) -3/2 * (-2,6) = -3/2 * (-26/10) = -3/1 * (-13/10) = 39/10 = 3,9
