0,2 : 3/16 = 2 2/3 : (0,4у -1,5)
1/5 * 16/3 = 8/3(2/5у- 3/2)
16/15 = 16/15у- 4
-16/15у= -4 - 16/15
-16/15у= - 5 1/15
-16/15у= - 76/15
у= 76/15 * 15/16
у= 4 3/4
7) 6m - 2,6=2,8m+1/15
3,2 m = 1/15 + 2 3/5
3,2 m = 1/15 + 13/5
3,2 m = 1/15 + 39/15
3,2 m = 40/15
3,2 m = 8/3
m = 8/3 : 3 1/5
m = 8/3 * 5/16
m = 5/6
8)
4(n +5/12)=1 1/6(6n-1 1/7)
4n + 5/3 = 7n - 4/3
-3n = -4/3 -5/3
-3n = -9/3
-3n = -3
n = -3 :(-3)
n = 1
