translation meaning verbs
Meaning of ぐらいでいいのでは in 「三回ぐらい噛んで飲み込めるぐらいでいいのでは？」
That ぐらい is 位, or "degree". So, translating it word by word, it's "Isn't it
enough by the degree in which you can bite it three times and swallow it?".
What it says is eventually "I think it's enough when you do it so that you
could bite it three times and swallow it".

Thanks to your additional info, OP, the question is now answerable.

So, the overall context is:

> Person A: "How should/could one eat elegantly while speaking to another?"
>
> Person B:
> 「[口]{くち}に[運]{はこ}ぶ[量]{りょう}を[少]{すく}なめにするといいと[思]{おも}いますよ。[三回]{さんかい}ぐらい[噛]{か}んで[飲]{の}み[込]{こ}める
> **ぐらいでいい** のでは？ 」

「～～ぐらいでいいのでは？」 is an expression of **suggesting a method** for an action. It
gives a _**rough**_ _**idea**_ of what should suffice in achieving a good
result, which should explain why 「ぐらい = "approximately"」 is being used.

「～～でいいのでは？」 = 「～～でいいのでは **ないでしょうか** ？」 if that helps you understand the phrase
better. It is a way of asking the question: "Wouldn't ~~ suffice?", "Wouldn't
~~ be good enough?"

What is the rough idea being suggested? It is "bringing a somewhat small
amount of food into your mouth at a time so that _**one could swallow**_ it
only after chewing it about 3 times".

To say " _ **one could swallow**_ ", it uses the potential form 「飲み込める」.
