Answer :
Rational numbers are numbers which can be written as a fraction (the formula is p/q). They don't include roots we can't solve in order to get a whole number and pi.
A. 776, pi, 25.209, √9 ---> NO (because of pi)
B. 726, 7/34, 20.209, √9 ---> YES
C. √3, 7/39, 20.3, √9 ---> NO (because of √3)
D. 726, 7/34, 20.209, √5 ---> NO (because of √5
Note that √9 = 3, so it IS a rational number.

Answer:
Option (B) is correct
Step-by-step explanation:
The rational number is in the form of [tex]\frac{x}{y}[/tex] , whereas x and y are the integers and q must not be equal to zero.
Rational number is also a terminating or if not terminating it should be
re-occurring.
Considering the option B
726 is a rational number
[tex]\frac{7}{34}[/tex] is also a rational number as per definition
20.209 is also a rational number
[tex]\sqrt{9}[/tex]= 3, is also a rational number
Hence, option (B) is correct.
