Answer 1

Question :

find a rational number between 3/8and 2/5.

Answer :

First of all make the denominators same .

• Take their LCM ( Least Common multiple )

The LCM is 40 .

Now , the numbers are

$\frac{15}{40} \: and \: \frac{16}{40}$

Now multiply both numbers by 10 . ( Both numerator and denominator )

$\frac{150}{400} \: and \: \frac{160}{400}$

Now , there are many rational numbers between them .

You can write any one .

I am writing

$\frac{151}{400}$

You can write anyone .

There are infinite rational numbers between them .

Rational numbers are those numbers which are in the form of p/q where both p and q must be integers and q≠0 .
