Question

十五分之十四,除以二十五分之八,乘以七分之二,加六分之一,的简便方法？

Answer 1

根据题意可知:
(14/15)÷(8/25)×(2/7)+(1/6)
＝(14/15)×(25/8)×(2/7)+1/6
＝(7/3)×(5/4)×(2/7)+1/6
＝(1/3)×(5/2)×(1/1)+1/6
＝(5/6)+(1/6)
＝6/6
＝1
分数运算之间，最主要的就是分子和分母的约分。多做题，自然就会了。

Answer 2

计算过程如下:
14/15÷8/25×2/7+1/6
=14/15×25/8×2/7+1/6
=（14/15×2/7）×25/8+1/6
=4/15×25/8+1/6
=5/6+1/6
=1
所以，最终答案是1。

Answer 3

=14/15*25/8*2/7+1/6
=14/15*25/4*1/7+1/6
=2/15*25/4*1+1/6
=2/3*5/4+1/6
=1/3*5/2+1/6
=5/6+1/6
=1
分别用2，7，5，2约分

Answer 4

14/15÷8/25×2/7+1/6
=14/15×25/8×2/7+1/6
=（14/15×2/7）×25/8+1/6
=4/15×25/8+1/6
=5/6+1/6=1

Answer 5

14/15÷8/25×2/7+1/6
=14/15×2/7×25/8+1/6
=4/15×25/8+1/6
=5/6+1/6
=1
