№ 1

0,25х * 1 1/3 = 2 5/6 * 2/17

25/100х * 4/3 = 17/6 * 2/17

1/4х * 4/3 = 1/3

1/4х = 1/3 : 4/3

1/4х = 1/3 * 3/4

1/4х = 1/4

х = 1/4 : 1/4

х = 1/4 * 4/1

х = 1

№ 3

1) 3/324 = 12/х

   3х = 12 * 324

   3х = 3888

   х = 3888 : 3

   х = 1296

2) 2/60 = 8/х

   2х = 8 * 60

   2х = 480

   х = 480 : 2

   х =240 дней
