There are "improper fractions"...

 

I don’t think so...

But I don’t know your definition of an irregular fraction.

To me a fraction is a real number that is expressed by a ratio of integers. Otherwise known as a rational number. Any number that isn’t rational is known as irrational. Like π or ε...

But you said irregular. What’s that?

I just heard what I thought was an irregular fraction being described as an improper fraction. Google comes up with 'improper' searching for irregular'.
I wondered if the naming had changed since the 60's when I was learning fractions.

 

A little digging seems to indicate that sometimes improper fractions are called irregular fractions. I hadn't heard it It was vaguely familiar, but it seems to exist as a term for the same thing.

I learned fractions at the time too, and it sounded familiar, but I knew improper was the right (current) term. It does seem that irregular gets some use and may be old.

Look at 1960, particularly in the second, isolated plot.

 

I was in junior high school in 1960. They have always been called improper fractions. I've never heard them referred to as irregular. In languages with verb conjugation there are a whole class of "irregular" verbs which do not follow one of a limited set of conjugation rules.

Just to mention, I’ve NEVER heard them called improper. Just irregular.

 

If you look at the ngram charts I posted you can see that improper is much more common but irregular peaks in the 60s.

US -- that certainly might account for it.

Regional difference is possible. I was in Ohio, Michigan and central New Jersey at that time.

 

if it were "friction" ,in sub-atomic world or thermodynamics it'd be a common concept.interaction between particles would claim various kind of irregularity.

No. A fraction is a fraction, is a fraction- which is a rational number.
