1/4+1/3+1/4+2/3
=(1/4+1/4)+(1/3+2/3)
=1/2+1
=1又1/2
运用加法结合律,把分母一样的两个分数一起相加,这样就可以不用通分,最后1/4+1/4=1/2,而1/3+2/3正好等于1,得到1有1/2,祝你学习进步!
=1/4+1/4+(1/3+2/3)
=1/2+1
=3/2
1/4+1/3+1/4+2/3
=(1/4+1/4)+(1/3+2/3)
=1/2+1
=1.5
以上就是计算过程。
1/4+1/3+1/4+2/3
=3/12+4/12+3/12+8/12
=3+4+3+8/12
=18/12
=3/2
1/4+1/3+1/4+2/3
=1/4+1/4+(1/3+2/3)
=1/2+1
=3/2
