Question

90.2×0.27+9.02×7.3的简便方法？

Answer 1

=90.2×0.27+90.2×0.73
=90.2×（0.27+0.73）
=90.2×1
=90.2
解法分析：提取公因数，凑整，然后按照四则运算法则进行运算，同级运算按顺序计算，不同级运算先算高级运算，再算低级运算，就可以很快得出结果。

Answer 2

简便计算过程如下
90.2×0.27+9.02×7.3
＝90.2×0.27+9.02×10×0.73
＝90.2×0.27+90.2×0.73
＝90.2×（0.27+0.73）
＝90.2×1
＝90.2
望采纳

Answer 3

90.2×0.27+9.02×7.3
=9.02×2.7+9.02×7.3
=9.02×（2.7+7.3）
=9.02×10
=90.2

Answer 4

90.2×0.27+9.02×7.3
=90.2×0.27+（9.02×10）×（7.3÷10）
=90.2×0.27+90.2×0.73
=（0.27+0.73）×90.2
=1×90.2
=90.2

Answer 5

原式＝90.2×0.27+90.2×0.73＝90.2×1＝90.2
