Question

7.26×4.8+72.6×5.3-0.726怎么简算？

Answer 1

你好，首先找到相同的数（726），把小数点平齐得原式等于0.726*48+0.726*530-0.726*1运用乘法分配律的逆运算，将原式化作0.726*（48+53-1）合并同类项的原式等于0.726*100，得结果为72.6

Answer 2

=7,26x4.8+7.26x53-7.26x0.1

=7.26x(4.8+53-0.1)
=7.26x57.7
怀疑你打错小数点了

Answer 3

7.26ⅹ4.8+72.6ⅹ5.3-0.726=72.6ⅹ0.48+72.6ⅹ5.3-72.6ⅹ0.01
=72.6ⅹ(0.48+5.3+0.01)
=72.6ⅹ6.29
=456.654
