Answer 1

6:0,3*5 = 6 : 3/10 * 5 = 6 * 10/3 * 5 = 2*10*5 = 100
6:0,3*1,2 = 6 : 3/10 * 12/10 = 6 * 10/3 * 12/10 = 6 * 4 = 24
6:0,3*0,27 = 6 : 3/10 * 27/100 = 6 * 10/3 * 27/100 = 2*27/10 = 54/10 = 5,4
6:0,3*0,63 = 6 : 3/10 * 63/100 = 6 * 10/3 * 63/100 = 2*63/10 = 126/10 = 12,6


1,2+0,36:0,02 = 1,2 + 36/100 : 2/100 = 1,2 + 36/100 * 100/2 = 1,2 + 18 = 19,2
1,2+0,36:3,6 = 1,2 + 36/100 : 36/10 = 1,2 + 36/100 * 10/36 = 1,2 + 1/10 = 1,2 + 0,1 = 1,3
1,2+0,36:0,1 = 1,2 + 36/100 : 1/10 = 1,2 + 36/100 * 10/1 = 1,2 + 36/10 = 1,2 + 3,6 = 4,8
1,2+0,36:0,9 = 1,2 + 36/100 : 9/10 = 1,2 + 36/100 * 10/9 = 1,2 + 4/10 = 1,2 + 0,4 = 1,6
