do you know the difference between rational and irrational?

anonymous · Answer

For the most part yes.

anonymous · Answer

so what part of the question is giving you trouble?

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.


An irrational number can be written as a decimal, but not as a fraction

how about $$\sqrt{28}$$=5.29
$$\sqrt{29}=5.38$$

anonymous · Answer

Wait, so i'm trying to find a rational number out of 5.2,5.3,5.4, and 5.5.  None of these can be written as a fraction because they aren't whole numbers. But would it be 5 and a half?

anonymous · Answer

what do you understand by rational numbers?  numbers can be expressed as the ratio of 2 integers, right? so you need to find out ratio of two numbers which give you value between 5.2 and 5.5
