4.3*0.23+0.43*5.5 =
4.3*0.23+4.3*0.55 = 4.3*(0.23 + 0.55) = 4.3* 0.78
11*0.086 = 11 * 0.02 * 4.3 = 4.3 * 0.22
4.3*0.23+0.43*5.5+11*0.086 = 4.3 * (0.78 +0.22) = 4.3 * 1 = 4.3
4.3*0.23+4.3*0.55 = 4.3*(0.23 + 0.55) = 4.3* 0.78
11*0.086 = 11 * 0.02 * 4.3 = 4.3 * 0.22
4.3*0.23+0.43*5.5+11*0.086 = 4.3 * (0.78 +0.22) = 4.3 * 1 = 4.3
