Решите уравнения
1) 4:х=14:49 2) 42:14=72:х
3) х:13=1,2:0,2 4)0,1:0,02=y:0,8
5)4,5:у=272,1 6) 2 1/3:у=12:18

1- x =4*49/14 =14

2- x = 14 *72/42 =24

3- x = 13 * 1.2/0.2 = 78

4- y = 0.8 *0.1/0.02 = 4

5-y =4.5/272.1

6-y = 7*18/12=10.5

1) х=14:49-4

2)х=72-42:14

3)х=1,2:0,2:13

4)у=0,8-0,1:0,02

5)у=272,1-4,5

6)у=12:18-2 1/3
