Question

((5/8-4/15):1/6+3 14/15): 0,8

Answer 1

((5/8 - 4/15) : 1/6 + 3 14/15) : 0,8 = 7 29/48
1) 5/8 - 4/15 = 75/120 - 32/120 = 43/120
2) 43/120 : 1/6 = 43/120 * 6/1 = 43/20
3) 43/20 + 3 14/15 = 129/60 + 236/60 = 365/60 = 6 5/60 = 6 1/12
4) 6 1/12 : 0,8 = 73/12 : 8/10 = 73/12 * 10/8 = 730/96 = 7 58/96 = 7 29/48
