Sometimes when we divide, we get answers which are too accurate and therefore don't make sense.

We must round the answer up or down to make sense of the question.

**Example**

How many coaches carrying 20 people will be needed to take 575 people to a football match?

**Answer**

575 ÷ 20 = 28.75

It is IMPOSSIBLE to have 28.75 coaches....so we need to THINK!!

28 coaches will not be enough.

So we need to round up to **29 **coaches.
