Answer:
B. [tex]\frac{-2}{3}[/tex]
Step-by-step explanation:
Rational Number is a number of the form [tex]\frac{p}{q}[/tex], where p & q are integers and q ≠ 0.
Further, Natural numbers can be a rational number.
Also, all repeating and terminating decimals are rational.
Option A is incorrect as π is an irrational number. So, if we multiply any number then the resulting number will also an irrational number.
Option B is correct as [tex]\frac{-2}{3}[/tex] is rational number and when multiply with any rational number or [tex]\frac{1}{5}[/tex] also produces a rational number. i.e. [tex]\frac{-2}{3}\times\frac{1}{5}=\frac{-2}{15}[/tex] = -0.1333333... as it is repeating decimal so it is rational number.
Options C and D are incorrect as -1.41421356.... and √11 are irrational numbers so when multiply with a rational number produces an irrational number.
