1) х:1/3 = 3/4:1/2. 3/4:1/2 = 3/4*2/1=3/2*1/1=3/2

Х:1/3 = 3/2

Х = 1/3*3/2. 1/3*3/2 = 1/3*3/2 = 1/1*1/2 = 1/2

Х = 1/2

2) 1 1/2:а = 4 3/4:2 3/8.

4 3/4:2 3/8 = 19/4*8/19 = 1/1*2/1 = 2

1 1/2:а = 2

А = 1 1/2:2. 1 1/2:2 = 3/2*1/2 = 3/4

А = 3/4

3) 2,8:3,2 = 2,1:х 2,8:3,2 = 2 4/5:3 1/5 = 14/5*5/16 = 7/1*1/8 = 7/8

2,1:х = 7/8

Х = 2,1:7/8. 2,1:7/8 = 2 1/10:7/8 = 21/10*8/7 = 3/5*4\1 = 12/5 = 2 2/5

Х = 2 2/5

4) 2 1/2:3 1/8 = у:2 2/3. 2 1/2:3 1/8 = 5/2*8/25 = 1/1*4/5 = 4/5

У:2 2/3 = 4/5

У = 2 2/3*4/5. 2 2/3*4/5 = 8/3*4/5 =32/15 = 2 2/15

У = 2 2/15

5) сори хз

6) 1/6:х = 2:3 3/7. 2:3 3/7=2/1*7/24=1/1*7/12 =7/12

1/6:х = 7/12

Х = 1/6:7/12. 1/6:7/12 = 1/6*12/7 = 1/1*2/7 = 2/7

Х = 2/7
