Answer 2

首先统一符号，小数，分数，百分数都可以，之后找到各个项的公约数，提出来即可。
25%+3.7×0.25+0.25×5.3
=0.25+3.7x0.25+0.25x5.3
=0.25×（1+3.7+5.3）
=0.25×10

=2.5

Answer 3

原试=1x0.25+3.7x0.25+0.25x5.3=（1+3.7+5.3）x0.25=10x0.25=2.5
先找到相同的数，然后全的转换为小数，最后用乘法分配律得到答案。

Answer 4

25%+3.7×0.25+0.25×5.3
=0.25×1+3.7×0.25+0.25×5.3
=0.25×（1+3.7+5.3）
=0.25×10
=2.5
望采纳 谢谢~~

Answer 5

25%+3.7x0.25+0.25x5.3
=0.25x1+0.25x3.7+0.25x5.3
=0.25x(1+3.7+5.3)
=0.25x10
=2.5
