Are there any real numbers that are both rational and irrational?Are there any real numbers that are neither?Explain your reasoning.
Answer the question,not translate the sentences!

都没有首先有理数集和无理数集从定义上来说是对立的所以不可能既是有理数又是有理数
实数集是有理数集合无理数集的并所以不存在实数不是有理数也不是无理数
至于具体的介绍你需要给一个有理数和无理数的定义从定义出发就可以证明了

Rational and Irrational numbers. let a,b and c be rational numbers and b=0.24-0.26a,c=0.26-0. If a,b,c,d are rational numbers(有理数),|a-b|≤9,|c—d|≤16 and |a 有人可以给我解释一下RATIONAL 和IRRATIONAL NUMBER的区别吗 let a,b and c be rational numbers and b=5分之12-5分之13a,c=5分之13 write the following rational numbers as quotients of two int rational.irrational这些都是什么数啊,我知道nature是自然数,还有实数无理数什么的英语怎么说然后列 read as "rational numbers are the set of all numbers a/b(是一个英语翻译THE POWER OF ALLOCATIONSystematic and rational allocatio Look_____the numbers below and write the numbers out _____ w upper and lower case letters and numbers. rational rotation
