# Grandpa and his silly questions. Another Grandpa mystery

An entry into the Topical Challenge #41 Short and Sweet

Grandpa was in one of his very silly "puzzling" mood.

"There is only one answer to the following", he quipped.

"Take a number between 0 and 9,

Split it into 3 to 2 ratio,

And there it is! follow me?"

"Only one answer?" I asked

"Yes. Get it?" He says with a smile.

I don't. Do you?

## 3 Answers

Take a number between 0 and 9, Split it into 3 to 2 ratio,

A number between 0 and 9 is a digit, which split 3:2, is dig it.

"And there it is! follow me?", ... , "Yes. Get it?"

And there it is! follow me? → showing it, and follow me means dig it
"Yes. Get it?" → it

Above is missing an explanation for the 'only one answer' parts, which kanoo does mathematically.

Is the answer

0

Because

Grandpa said 'There it is' after performing the 3:2 ratio math, as though implying the number originally selected was seen again. The only number that can multiply or divide by any other rational number and still be itself is 0.

Well isn't it

3 and 2

because

only 5 is divisible by 5, so it's the only one that can be split 3-to-2, so the result can only be 3 and 2.

This is marked 'short and sweet'... but even so, that seems too easy. And there's the point that

mathematically, 0 is also divisible by 5, so 0 and 0 should also be an answer. And there's only supposed to be one answer. However, mathematical convention about degenerate cases often does not apply to english words, so this might not count as a split.
