答案:0.38

4/14+8/14=6/7 

7/10+2/10=9/10 

2/38/16=3/4

5/8X4=5/2

注:代表分号,/代表除号,21表示二分之一,5+41=5 41表示5又4/1(带分数)*为乘号

与整数运算中的“凑整法”相同,在分数运算中,充分利用四则运算法则和运算律(如交换律、结合律、分配律),使部分的和、差、积、商成为整数、整十数...从而使运算得到简化。

注意事项

①分母一定不能为0,因为分母相当于除数。否则等式无法成立,分子可以等于0,因为分子相当于被除数。相当于0除以任何一个数,不论分母是多少,答案都是0。

②分数中的分子或分母经过约分后不能出现无理数(如2的平方根),否则就不是分数。

③一个最简分数的分母中只有2和5两个质因数就能化成有限小数;如果最简分数的分母中只含有2和5以外的质因数那么就能化成纯循环小数;如果最简分数的分母中既含有2或5两个质因数也含有2和5以外的质因数那么就能化成混循环小数。
