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
