Question

6.74x5.3 0.53X32.6怎么简便计算？

Answer 1

6.74×5.3+0.53×32.6
=6.74×5.3+5.3×3.26
=5.3×（6.74+3.26）
=5.3×10
=53
乘法分配律

Answer 2

面便计式是：原式＝6.74x5.3＋5.3x3.26＝（6.74＋3.26）x5.3＝10x5.3＝53。

Answer 3

6.74×5.3+0.53×32.6＝6.74×5.3+3.26×5.3＝（6.74+3.26）×5.3=10×5.3＝=53 根据乘法分配率

Answer 4

6.74×5.3+0.53×32.6
＝6.74×5.3+0.53×10×3.26
＝（6.74+3.26）×5.3
＝10×5.3
＝53

Answer 5

6.74×5.3+0.53×32.6＝6.74×10＝0.53+0.53×32.6＝0.53×（6.74×10+32.6）＝0.53×100＝53
