A rational number is one that has an ending.
It depends on if it is continued or not. A terminal decimal is always rational (such as 0.5) If it has a repeating pattern, its also rational (0.3333333333333333). If you mean 0.50550555055550555550555555 etc.) this is not rational.
If you mean 213 then it is a rational number because all integers or whole numbers are rational numbers.
It is neither but if you mean the square root of 100 then it is 10 which is a rational number
0.3 is a rational number. The fact that it is expressed as a decimal does not mean it is not rational. As a ratio, it can be written as 3/10.
Magophobia
Of course not, there is no rational argument against homosexuality.
The completely rational fear of lady birds :)
False Evidence Appearing Rational
The word "rational" is usually considered the opposite of "emotional" and fear is an emotion so, on the face of it, it might seem that to speak of a "rational fear" is an oxymoron. This is only the case if the two really are opposites and many would not agree. Aristotle is one of them. He points out that reasons should always rule, and that includes ruling the emotions. That would put reason over emotion and not necessarily in opposition to it. A rational fear, as opposed to an irrational or emotional fear, would be one that is based on good reason(s). For instance, fear of leaving a candle burning when you retire for the evening is a rational fear - since it's likely to burn down the house in which you're sleeping. An irrational fear would be a fear of sleeping with fewer than four pillows - at least unless there's some good reason that you NEED four pillows to sleep safely (not fall off the bed, for instance). Concerning a race of people, there can be no rational fear. A rational fear is based on experience and we don't (and can't) have adequate experience with enough members of a race of people to have good reason to fear them. Concerning groups of people, the answer is not as clear. It is rational to fear murderers, for instance, even if we've never met a single one of them, because of the very thing that defines them as a group. It isn't rational to fear all gang members, as they aren't all criminals or otherwise "bad" people, but it's certainly rational to be very cautious of them since so many of them are and we have no way of knowing which specific ones there wouldn't be good reason to fear. Fearing people who are members of a large group is seldom rational, since there are going to be all kinds of different people in that group. The groups of people who identify themselves as atheists or Christians, as Democrats or Republicans, as single people or not - all of those groups are too large to warrant fearing them all, e.g. fearing the whole group. Roughly, a "rational fear" is one for which there are good reasons, instead of being based on emotions without considering whether those emotions have any basis is reason. The better the reasons to feel the emotion, the more rational the fear; the weaker the reasons to feel the emotion, the less rational the fear.

A phobia is an irrational fear. So rational fears are not phobias - being afraid of bears is a rational fear if your are in bear country, but an irrational one if you are at a zoo. Non-phobias don't have names, and so cannot be listed.
Parudophobia is the non rational fear of pairing socks
It mean like chocked up with fear or restricted with fear
yes rational means repeating. same thing.
If you mean 4/9 as a fraction then it is a rational number
