简便计算;3.24×4分之1+0.25×4.76简便计算;3.24×4分之1+0.25×4.76简便计算;3.24×4分之1+0.25×4.763.24×4分之1+0.25×4.76=(3.24+4.

简便计算;3.24×4分之1+0.25×4.76
简便计算;3.24×4分之1+0.25×4.76

简便计算;3.24×4分之1+0.25×4.76
3.24×4分之1+0.25×4.76
=(3.24+4.76)×0.25
=8×0.25
=2

=3.24×0.25+4.76×0.25
=(3.24+4.76)×0.25
=8×0.25
=2.

首先要知道0.25=1/4
3.24*1/4+0.25*4.76=0.25*(4.76+3.24)=2

3.24×4分之1+0.25×4.76
=0.25×(3.24+4.76)
=0.25×8
=2

3.24×4分之1+0.25×4.76
=3.24x1/4+1/4x4.76
=(3.24+4.76)x1/4
=8/4
=2

3.24+4.76=8
8*0.25=2

3.24×4分之1+0.25×4.76
=(3.24+4.76)×0.25
=8×0.25
=2

天啊。难道是小学生?那么简单?还是前面那个3.24×4分之1是乘完后咧还是乘以0.25.。唉
纠结

4分之1×(3.24+4.76)=4分之1×8=2

=(3.24+4.76)×0.25
=8×0.25
=4×0.25×2
=1×2
=2

简便计算:
3.24×4分之1+0.25×4.76
=1/4*(3.24+4.76)
=1/4*8
=2
