A rational number between √2 and √3 is
a. (√2 + √3)/2
b. √2.√3/2
c. 1.5
d. 1.8

Solution:

We know that

√2 = 1.41

√3 = 1.73

We have to find the rational number between √2 and √3

i.e. we should determine the rational number between 1.41 and 1.73

From the given options, 1.5 is the rational number which lies between 1.41 and 1.73

Therefore, the rational number is 1.5.

✦ Try This: A rational number between √3 and √5 is a. (√3 + √5)/2, b. √3.√5/2, c. 2.0, d. 2.5

We know that

√3 = 1.73

√5 = 2.23

We have to find the rational number between √3 and √5

i.e. we should determine the rational number between 1.73 and 2.23

From the given options, 2.0 is the rational number which lies between 1.73 and 2.23

Therefore, the rational number is 2.0
