Answer 1

Depends on what they want you to round up to.

Answer 2

It looks like they want whole numbers.
Here's a rule to remember for any digit rounding (digit x)\[x\lt5,\text{ round down}\rightarrow x\ge5,\text{ round up}\]

Answer 3

Well, specifically I think they want 10s and 100s.\[404.31\rightarrow\text{ Digit x is 4, round down to 400}\]\[48.031\rightarrow\text{ Digit x is 8, round up to 50}\]\[\text{So }\frac{404.31}{48.031}\rightarrow\frac{400}{50}=??\]

Answer 4

I'm confused
