1) 0.45×4.6+4.5×6.8-26×0.045
=0.45x(4.6+6.8-2.6) = 0.45x8.8 = 0.9x4.4 = (1-0.1)x4.4 = 4.4-0.44 =4-0.04 = 3.96
5) 0.89x98+0.2x8.9 = 8.9x(9.8+0.2) = 89
6) 10.01x65-0.65 = 65 + 0.65-0.65 = 65
=0.45x(4.6+6.8-2.6) = 0.45x8.8 = 0.9x4.4 = (1-0.1)x4.4 = 4.4-0.44 =4-0.04 = 3.96
5) 0.89x98+0.2x8.9 = 8.9x(9.8+0.2) = 89
6) 10.01x65-0.65 = 65 + 0.65-0.65 = 65
