贵刊在1991年第七期、1992年第五期上都发表了关于“3/4<( )<4/5有无穷多解”的文章,两篇文章都给出了解3/4<( )<4/5的方法。本文想给出一种解这一题目的简单方法,以及这种方法的理论依据。要在3/4<( )<4/5的括号内填上合适的数,使得不等式成立,这个数可以这样得到:把括号两边两个分数分母的和作为新的分母,两个分子的和作为
Your publication published an article on “3/4 <() <4/5 with infinitely many solutions” in the seventh issue in 1991 and the fifth issue in 1992, and both articles give an understanding of 3/4 <( ) <4/5 method. This article wants to give a simple solution to this problem, as well as the theoretical basis for this method. To put the appropriate number in brackets 3/4 <() <4/5 so that the inequality holds, this number is obtained by taking the sum of the two fractional denominators on both sides of the parentheses as the new denominator, the sum of the two molecules As
