Adverb usage correct?

I’m messing around making sentences with adverbs.

こたえ を しょうじきに きめました。

This means “I decided the answer honestly,” right?

Would しょうじきな こたえ を きめました be “I decided the honest answer” ?

Thanks in advance!

Looks fine grammatically. Not sure if the sentence means anything though. How about:

しょうじきなこたえをあげました。
しょうじきなこたえを出しました。

Yeah, I agree that the usage of しょうじき isn’t a problem on its own, but it sounds odd to “decide an answer”.

Cool thank you both!!
