Question

Insert three rational numbers between 7 and 8.

Answer 1

To insert three rational numbers between 7 and 8, we simply choose any three numbers that are:

• Greater than 7
• Less than 8
• And are rational i.e., can be expressed as fractions

Example:

• 7.5
• 7.7
• 7.8

These are all rational since

`7.5 = 15/2` 

`7.7 = 77/10` 

`7.8 = 39/5`
