Question

五点52×1点8 +55点2×0点八二？

Answer 1

计算过程如下

5.52×1.8+55.2×0.82

＝5.52×10×0.18+55.2×0.82

＝55.2×0.18+55.2×0.82

＝55.2×（0.18+0.82）

＝55.2×1

＝55.2

望采纳

Answer 2

5.52x1.8+55.2x0.82
=0.552ⅹ18+0.552x82
=0.552ⅹ(18+82)
=0.552x100
=55.2

Answer 3

5.52×1.8＋55.2×0.82
＝5.52×1.8＋5.52×8.2
＝5.52×(1.8＋8.2)
＝5.52×10
＝55.2

Answer 4

5.52x1.8+55.2x0.82
=55.2x0.18+55.2x0.82
=55.2x(0.18+0.82)
=55.2x1
=55.2
