Answer 1

4.32×7.3+0.27×42.3
=4.32×7.3+2.7×4.23
=4.32×7.3+2.7×4.32 -2.7x0.09
=4.32x(7.3+2.7) -0.243
=43.2-0.243
=42.957

Answer 2

4.32×7.3+0.27×43.2
=（43.2×0.1）×7.3+0.27×43.2
=43.2×（0.1×7.3）+0.27×43.2
=43.2×0.73+0.27×43.2
=43.2×（0.73+0.27）
=43.2×1
=43.2
你应该是不小心写错了一个数字吧

Answer 3

4.32×7.3+0.27×43.2
＝4.32×7.3+2.7×4.32
＝4.32×（7.3+2.7）
＝4.32×10
＝43.2

Answer 4

4.32×7.3+0.27×42.3
=4.32×7.3+0.27×10×4.32
=4.32×（7.3+0.27×10）
=4.32×10
=43.2

Answer 5
