PLz tell nowwww

Answer 1

Answer:

A rational number between two numbers a and b=

2

(a+b)

So, a rational number between −1 and −2=

2

−1−2

=

2

−3

Now, another rational number between −1 and

2

−3

=

2

−1+

2

−3

=

4

−5

And another rational numbers between

2

−3

and −2=

2

2

−3

−2

=

4

−7

Answer 2

Step-by-step explanation:

A rational number between two numbers a and b=2(a+b)

A rational number between two numbers a and b=2(a+b)So, a rational number between −1 and −2=2−1−2=2−3 

A rational number between two numbers a and b=2(a+b)So, a rational number between −1 and −2=2−1−2=2−3 Now, another rational number between −1 and 2−3=2−1+2−3=4−5

A rational number between two numbers a and b=2(a+b)So, a rational number between −1 and −2=2−1−2=2−3 Now, another rational number between −1 and 2−3=2−1+2−3=4−5And another rational numbers between 2−3 and −2=22−3−2=4−7
