V1a9 · Answer

1) 1 7/12/(3/8+5/12) = 19/12: (18/48+20/48) = 19/12: 38/48 = 19/12*48/38 =2
2) 17/36/(3/8+5/12) = 17/36: (18/48+20/48) = 17/36: 3848 = 17/36*48/38 = 34/57
3) (3/14+5/7)/3 5/7 = (3/14+10/14): 26/7 =13/14: 26/7 = 13/14*7/26 = 1/4 = 0,25
4) 19/24/(3/16+5/24) = 19/24: 19/48 = 19/24*48/19 = 2
