五年级下册加减分数口算

如下:

(1)1/7+3/8+5/7=1/7+5/7+3/8=6/7+3/8=48/56+21/56=69/56

先分母相同进行运算,再约分。

(2)1-5/9-4/9=1-(5/9+4/9)=1-1=0

连减几个数,等于减去这几个数相加。

(3)4/11+5/6-4/11=4/11-4/11+5/6=0+5/6=5/6

同分母先进行运算。

(4)3/4-1/6+1/4=3/4+1/4-1/6=1-1/6=5/6

符号跟在后一个数前,移动时要带上符号。

(5)7/8-(1/5+1/3)=7/8-(3/15+5/15)=7/8-8/15=41/120

这个没有技巧,只能通分。

(6)1+(1/3-1/6)=1+(2/6-1/6)=1+1/6=1又1/6

通分时别忘分子也要乘。

乘除法

1、分数乘整数,分母不变,分子乘整数,最后能约分的要约分。

2、分数乘分数,用分子乘分子,用分母乘分母,最后能约分的要约分。

3、分数除以整数,分母不变,如果分子是整数的倍陪岁数,则用分子除以整数,最后能约分的要约分。

4、分数除以整数,分母不变,如纳亩果分子不是整数的倍数,则用这个分数乘这个整数的倒数,最后能约分的要约分。
