### Access Answers to RS Aggarwal Solutions for Class 8 Maths Chapter 1- Rational Numbers Exercise 1F

1. Find the rational number between Â¼ and 1/3

Solution: Let us consider the rational number as x

So to find the rational number between Â¼ and 1/3

By using the formula x= Â½ (a/b + c/d)

x = Â½(1/4 + 1/3)

by taking the LCM for 4 and 3 we get,

x = Â½((1Ã—3 + 1Ã—4)/12)

= Â½((3+4)/12)

= Â½(7/12)

= Â½ Ã— 7/12

= 7/24

âˆ´ the rational number between Â¼ and 1/3 is 7/24.

2. Find the rational number between 2 and 3

Solution: Let us consider the rational number as x

So to find the rational number between 2 and 3

By using the formula x= Â½ (a/b + c/d)

x = Â½(2 + 3)

x = Â½(5)

= 5/2

âˆ´ the rational number between 2 and 3 is 5/2.

3. Find the rational number between -1/3 and 1/2

Solution: Let us consider the rational number as x

So to find the rational number between -1/3 and 1/2

By using the formula x= Â½ (a/b + c/d)

x = Â½(-1/3 + 1/2)

by taking the LCM for 3 and 2 we get,

x = Â½((-1Ã—2 + 1Ã—3)/6)

= Â½((-2+3)/6)

= Â½(1/6)

= Â½ Ã— 1/6

= 1/12

âˆ´ the rational number between -1/3 and 1/2 is 1/12.

4. Find two rational number between -3 and -2

Solution: Let us consider the rational number as x

So to find the rational number between -3 and -2

By using the formula x= Â½ (a/b + c/d)

x = Â½(-3 + (-2))

= Â½(-3-2)

= Â½(-5) = -5/2

Now we find the rational number between -5/2 and -2. Since -5/2 also lies between -3 and -2.

Let us consider another rational number as y

So let us use the formula again

y= Â½(-5/2 + (-2))

= Â½ ((-5/2)-2)

= Â½ ((-5-4)/2)

= Â½ (-9/2)

= Â½ Ã— -9/2

= -9/4

âˆ´ Two rational numbers between -3 and 2 is -5/2 and -9/4.
