(8 3/5 - 60) : (8,3 + 4/19 - 15/38) = - 6 1/3
1) 8 3/5 - 60 = 8,6-60=-51,4
2) 8,3 + 4/19 = 8 3/10 + 4/19 = 8 57/190 + 40/190 = 8 97/190
3) 8 97/190 - 15/38 = 8 97/190 - 75/190 = 8 22/190 = 8 11/95
4) -51,4 : 8 11/95 = -51 4/10 : 8 11/95 = -51 2/5 : 8 11/95 = -257/5 : 771/95 = - 257/5 * 95/771 = -19/3 = -6 1/3
