=37.2
满意记得给分啊

Answer 3

这道题可以利用乘法分配率来实现简算:
乘法分配率字母表示：
(a+b)×c=a×c+b×c
3.72*6.5+2.5*3.72+3.72
=3.72*6.5+3.72*2.5+3.73
=3.72*(6.5+2.5+1)
=3.72*10
=37.2

Answer 4

3.72×6.5+2.5×3.72+3.72
=3.72×（6.5+2.5+1）
=3.72×10
=37.2

Answer 5

可以提取公因式3.72
3.72×6.5+2.5×3.72+3.72
=3.72×（6.5+2.5+1）
=3.72×10
=37.2
所以答案为37.2。
