Answer 1

(2 13/48 -(-2 5/12)) / (-3 3/4) + 9 3/4 / (-13)  = (109/48 + 29/12) / (-15/4 +39/4 /(-13) =
(109/48 +116/48) / (-15/4 -3/4) =   225/48 / (-18/4) = -225/216  = 1 9/216 = - 1 1/24
2) (1 2/3 - 3,6) / (-2 7/9 + 4 1/15) * (-2,6) = (5/3 -36/10) / (-25/9 +61/15) * (-26/10) =
     (50/30 - 108/30) / ( -125/45 +183/45) * (-13) = (-58/30) /(58/45) * (-13) =
-3/2 *(-13) = 39/2 =19 1/2 = 19,5
