Question

Which integer is closer to a number of the form x+0.5, where x is an integer? x or x+1?

Answer 1

This sounds like a rounding problem. Which do you think is the answer.

Answer 2

I need a definition of 'closer to' to answer the problem, because I'm solving some problems which talk about an integer closer to a number and I'm confused for the case where the number is like 2.5. Is it closer to 2 or 3?

Answer 3

I always round up. But sometimes teachers have different rules. For 2.5, I would round up to 3

Answer 4

Okay, I'll just ask my teacher about this.
