Question

4.75×3.78 4.75×2.57 5.25×6.35简便方法？

Answer 1

脱式计算4.75×3.78+4.75×2.57+5.25×6.35
解题思路：四则运算规则（按顺序计算、先算乘除后算加减，有括号先算括号，有乘方先算乘方）即脱式运算（递等式计算）需在该原则前提下进行
解题过程：
4.75×3.78+4.75×2.57+5.25×6.35
=4.75×(3.78+2.57)+5.25×6.35
=(4.75+5.25)×6.35
=10×6.35
=63.5

Answer 2

4.75×3.78+4.75×2.57+5.25×6.35
=4.75×（3.78+2.57）+5.25×6.35
=4.75×6.35+5.25×6.35
=（4.75+5.25）×6.35
=10×6.35
=63.5

Answer 3

答案是63.5

Answer 4

=4.75×（3.78+2.57）+5.25×6.35
=4.75×6.35+5.25×6.35
=6.35×（4.75+5.25）
=6.35×10
=63.5
