Significant figure rounding.

[Joza]

6.0221367 is a number rounded to 8 significant figures.

In a question, I am asked which of these shows correct rounding off.

6.022

6.0

6.02214

Aren't they all correct? It does not specify to how many figures.

[Doc Al]

They all look correct to me.

[Joza]

I know.

And it is a question for an online tutorial. I don't know what to do.

[Joza]

Ideas?
