plz answer fast write on paper​

Answer 1

Answer:

-7/4

Step-by-step explanation:

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

Since we want the five rational number between 2 and 3 

The numbers of denominator 5+1=7

So 2=1×62×6=612

And 3=1×63×6=618

We know that 12<13<14<15<17<18

And 612<613<614<615<616<617<618

Hence five rational number between 2 and 3 are

613,614,615,616,617
