3.54x16.88+17.7x6.624怎么简算？

Answer 1

计算时将3.54变换成17.7×0.2然后在进行运算，就可简便，计算如下：
3.54×16.88+17.7×6.624=17.7×0.2×16.88+17.7×6.624=17.7×3.376+17.7×6.624=17.7×(3.376+6.624)=17.7×10=177

Answer 2

简便计算找相同、找互补、找倍数。
3.54×16.88+17.7×6.624
＝3.54×16.88+3.54×5×6.624
＝3.54×（16.88+5×6.624）
＝3.54×（16.88+33.12）
＝3.54×50
＝177

Answer 3

3.54×16.88+17.7×6.624
=35.4×1.688+17.7×2×3.312
=35.4×1.688+35.4×3.312
=35.4×（1.688+3.312）
=35.4×5
=177

Answer 4

3.54×16.88+17.7×6.624
=3.54×16.88+3.54×5×6.624
=3.54×16.88+3.54×(5×6.624)
=3.54×16.88+3.54×33.12
=3.54×(16.88+33.12)
=3.54×50
=177

Answer 5

=17.7（0.2*16.88+6.624）
=17.7*10
=177
