The most ever ...

Can someone help me with the following kinds of (partial) sentences:

The most he'd ever eaten

The happiest she'd ever been

The farthest they'd ever traveled

There are more somei yoshino in Georgia than anywhere else in the US.

"The most he'd ever eaten"
- Ichiban takusan tabeta toki (when he's eaten the most (amount) ever)

"The happiest she'd ever been"
- Kanojo ga ichiban shiawase datta toki (the time when she's the happiest ever)

"The farthest they'd ever traveled"
- Ichiban tooku made ryokou shita toki (the time when they traveled farthest)

"THere are more somei yoshino in Georgia than anywhere else in the US"
- US no doko yori, Joojia ni wa somei yoshino ga takusan arimasu.

Thanks, AK.

So would this be correct:

一番高く上った時

How about:

それは彼が一番高く上った時だった。

Do you mean "climb" (like mountain climbing)? Then it should be 登った.

I would want to know the context of that sentence too. This one says "It was when he went to the highest." (And it sounds a bit like "something happened when he went to the highest.)

Yes, mountain climbing. Thanks.

For context, how about: He climbed high in the Alps, and higher on 富士山. But on that trip to the Himalayas, he climbed the highest ever.
