а) 1х/18 = 1/3 б) 1х/4 = 1/16 в) 1х/7 = 1/14 г) 1х/2 = - 1/12
    х = 6   4х = 1 2х = 1 6х = -1
           х = 1/4    х = 1/2    х = - 1/6

№206
а) х/7 = - 1/14 б) -х/20 = 1/10 в) - х/15 = 1/45 г) х/21 = 1/7
   2х = - 1 - х = 2 -3х = 1 х = 3
   х = - 1/2    х = -2    - х = 1/3
      х = - 1/3

№207
а) - х/100 = - 1/25 б) х/25 = - 1/75 в) -х/64 = - 1/8 г) х/90 = -1/30
   х = 4    3х = - 1 - х = - 8 х = -3
   х = -1/3 х = 8
