Is there a shorter term for "divided by" in American English?

Given the following expression:

5 (+-×÷%) 4

You would say "5 plus 4," "5 minus 4," "5 times 4," "5 divided by 4," and "5 mod(ulo) 4" respectively.

As far as I know, "divided by" does not have any shorthand form in the same way the above examples do.

Solution 1:

Perhaps alternatives suffice to the extent that no great pressure exists to shorten "divided by"?

"5 over 4"?

"five fourths"?

Solution 2:

What about "per"? While not usually used in the same context as plus, minus, etc., it does mean "divided by".

Solution 3:

Invert the question/problem

4 into 5 goes 1.2 was the way I was brought up...

Solution 4:

I would use "5 by 4" in a generic setting like @Jasper mentioned. @Stan's point is valid, however in a matrix setting we're usually specific, like "A five by four matrix". From what I've seen/heard/experienced, "5 times 4" is the colloquial norm for multiplication and "5 by 4" is the colloquial norm for division.
