Question

8.88ⅹ3.6+25.3ⅹ0.64+6.35ⅹ6.4等于多少简便运算？

Answer 1

8.88×3.6+25.3×0.64+6.35×6.4
=8.88×3.6+2.53×6.4+6.35×6.4
=8.88×3.6+(2.53+6.35）×6.4
=8.88×3.6+8.88×6.4
=8.88×(3.6+6.4）
=8.88×10
=88.8

Answer 2

8.88×3.6+25.3×0.64+6.35×6.4
=8.88×3.6+2.53×6.4+6.35×6.4
=8.88×3.6+(2.53+6.35)×6.4
=8.88×3.6+8.88×6.4
=(3.6+6.4)×8.88
=10×8.88
=88.8

Answer 3

=8.88＊3.6+2.53＊6.4+6.35＊6.4
=8.88*3.6+（2.53+6.35）*6.4
=8.88*3.6+8.88*6.4
=8.88*（3.6+6.4）
=88.8

Answer 4

=1.11×8×9×0.4+25.3×3.2×0.2+6.35×3.2×2
=3.2×9.99+3.2×5.06+3.2×12.7
=3.2×(9.99+5.06+12.7)
=3.2×(15.05+12.7)
=3.2×37.75
=3.2×(40－2.25)
=3.2×40－3.2×(2+1/4)
=128－6.4-0.8
=128－7.2
=120.8

Answer 5

8.88×3.6+25.3×0.64+6.35×6.4
=8.88×3.6+6.4×（2.53+6.35）
=8.88×3.6+6.4×8.88
=8.88×（3.6+6.4）
=8.88×10
=88.8
