11.4×0.25+0.86×2.5的简便运算
11.4×0.25+0.86×2.5的简便运算

11.4×0.25+0.86×2.5的简便运算
11.4×0.25+0.86×2.5
=11.4×0.25+8.6×0.25
=(11.4+8.6)×0.25
=20×0.25
=5

=11.4*0.25+8.6*0.25
=0.25*(11.4+8.6)
=0.25*20
=5

11.4×0.25+0.86×2.5=11.4×0.25+8.6×0.25=0.25×(11.4+8.6)=0.25×20=5

10*0.25+1*0.25+0.25*0.4+0.8*2.5+0.06*2.5
2.5+0.25+0.1+2+0.15
5
或者
1.14*0.25+0.86*2.5
(1.14+0.86)*2.5
5

11.4×0.25+0.86×2.5
= 1.14×2.5 + 0.86×2.5
= (1.14 + 0.86)×2.5
= 2×2.5
= 5
