Answer 2

Answer:

Given:

To find:

•  rational no. Between 4 and 5

Solving Question:

Rational number: The number which can the written in the form of p/q

where q ≠ 0

we can find the answer using the formula $\dfrac{a+b}{2}$ or the common method to make them in the fractions with same denominators and find answer.

Solution:

Here I am using the formula   $\dfrac{a+b}{2}$

⇒ a = 4

   b = 5

Thus, the number = $\dfrac{a+b}{2}\\\\\implies \dfrac{4+5}{2}=\dfrac{9}{2}=4.5$

 ∴ The new number is 4.5

To find the next number take ,

a = 4

b = 4.5

$\implies \dfrac{4+4.5}{2}=\dfrac{8.5}{2}=4.25$

∴ The new number is 4.25

To find the next number take ,

a = 4

b = 4.25

$\implies \dfrac{4+4.25}{2}=\dfrac{8.25}{2}=4.125$

∴ The new number is 4.125

Hence, the numbers are 4.125 , 4.25 , 4.5 .
