Answer 1

Let's check them if they obeys rationality

• 4.2=42/10
• 1.6=16/10
• 1.05=105/100
• 0.8=8/10

Yes they do

So they belongs to set of rational numbers i.e Q

Answer 2

a) rational numbers

**the completed number lines are attached**

Explanation:

a) The numbers in set 1 are all rational numbers as they can all be written in the form
`(p)/(q)` where q ≠ 0.

`4.2 =(21)/(5)`

`1.6=\frac85`

`1.05=(21)/(20)`

`0.8=\frac45`
