1)1) 14/25 * 10/21= 4/15

2) 6 * 2 1/3= 6 * 7/3= 14

3) 2/9 * 3/8= 1/12

4) 3/7 * 21= 9

5)3 1/5 * 15/24 = 16/5 * 15/24= 2

6)33/48 * 12/21= 11/28

7/1,2 * 1 1/9 = 1 1/5 * 10/9= 6/5 * 10/9= 4/3 = 1 1/3

8) 27 * (2/3)^2*1 7/8= 27*4/9 * 15/8= 22 1/2

2) (3/5 +1/7) * 35= 105/5 + 35/7= 17 + 5 = 22

2 3/13* 4 5/9 - 2 3/13 * 1 5/9= 2 3/13*(4 5/9 - 1 5/9)= 2 3/13 * 3= 29/13 * 3= = =87/13= 6 9/13

3)5/14х -9/28х + 11/42х= 30/84х- 27/84х + 22/84х= 25/84х

8/9 х * 1 4/5 у= 8/9х * 9/8у = х*у
