What is 41.2 * 8.1 + 5.37 * 19 + 1.1 * 91.5

(40 + 1.2) * (8 + 0.1) + (5 + 0.37) * (20-1) + (1 + 0.1) * (90 + 0.15) is using the multiplication distribution law

41 and a fifth times 8.1 plus 5.37 times 19 plus 1.1 times 92 and a half

41 and a fifth times 8.1 plus 5.37 times 19 plus 1.1 times 12 and a half
=4.12x81+4.12x19+1.25x19+11x1.25
=4.12x(81+19)+1.25x(19+11)
=4.12x100+1.25x30
=412+37.5
=449.5
