The teacher announced that the class would be learning more about rational numbers.

An English major raised his hand and said that numbers weren’t rational After all; a number certainly couldn’t think let alone be rational!

‘The teacher said she didn’t mean that kind of rational.

Another student said she’d heard numbers could be rational; as well as irrational; but she didn’t think it
had anything to do with thinking.

The teacher agreed. The root in the word ‘rational’ is ratio”. A rational number is simply a number that can be written as the ratio of an integer and a nonzero integer.

Someone asked if that definition would be on the test, and if so, would it be on an English test or math test?
