1\6х-0,82=3\8х-1,37
4/24x - 9/24x = -1,37 + 0,82
-5/24x = -0,55
х=0,55*24/5
x=2,64
1) 6 11/15 - 4 3/20 = 101/15 - 83/20 = 404/60 - 249/60 = 155/60 = 31/12 = 2 7/12
2)18,6:2 7/12 = 18 6/10 : 2 7/12 = 93/5 : 31/12 = 93/5 * 12/31 = 36/5 = 7 1/5
3)20 - 7 1/5 = 20 - 36/5 =100/5 - 36/5 = 64/5 = 12 4/5=12,8
ответ12 4/5 или 12,8
