Answer 1

Step-by-step explanation:

we know that all integers, terminating

decimal numbers, non terminating

repeating decimal numbers, perfect

square decimal numbers , fractions

are rational numbers.

therefore

(I),(ii),(III) (v),(vii) are integers=> rational numbers

(iv) = √1.44= 1.2= terminating decimal number

=> rational number

(x) and (xi) are non terminating repeating decimal numbers=> rational numbers

(viii) and (ix) non terminating non repeating decimal

numbers => irrational numbers
