# 3.1 Thinking more about fractions

The next activity is different from the numerical activities you’ve seen so far: it asks you to consider some general statements about fractions and decide whether they are true or false. This will give you the chance to think more about what a fraction is.

## Activity 3 True or false?

a.

True

b.

False

The correct answer is b.

### Comment

False. The fraction could be or , which are both bigger than one half. Be careful! The use of the word ‘only’ may suggest to you that it is a small fraction, perhaps less than one half, but this could be a wrong interpretation.

a.

True

b.

False

The correct answer is a.

### Comment

True. A fraction can be thought of as a division problem. For example, is the same as . However, some decimal fractions do not stop; instead they have a repeating set of digits, such as These are known as **recurring decimals**. They are accurately represented by placing a dot over the first and last numbers of the repeating set, like this: .

Often, these decimal numbers are rounded, so you might see rounded to 0.29 or 0.286. Keep in mind that rounded values, while useful for some purposes, are not the same accurate representations as fractions.

a.

True

b.

False

The correct answer is b.

### Comment

False. But don’t worry if you said true! This is something new, and is a bit tricky. We can have fractions that are equal to one (e.g. is equal to 1) or even bigger than one (e.g. (seven-thirds) has a value greater than 1 because it means , which is greater than 2. You will look more at fractions like this later this week.

Now, back to working with specific numbers, rather than general rules! In the next section you are going to look at mixed numbers – these consist of both a fraction and a whole number.
