Question

Insert rational number between 2.1 and 2.2

Answer 1

Step-by-step explanation:

Given rational nos are 2.1 and 2.2

To find: 16 rational nos between them

First we find their Equivalent rational nos. such that there exist 16 or more than 16 rational no between them.

Consider,

2.1\:\:\:and\:\:\:2.2

⇒ \frac{21}{10}\:\:\:and\:\:\:\frac{22}{10}

⇒ \frac{21}{10}\times\frac{100}{100}\:\:\:and\:\:\:\frac{22}{10}\times\frac{100}{100}

⇒ \frac{2100}{1000}\:\:\:and\:\:\:\frac{2200}{1000}

Now there exist 100 rational nos between them

16 from them are the following,
