Answer 2

Answer:

IT HAS A TERMINATING DECIMAL EXPANSION

0.12

Step-by-step explanation:

3/25

= 3/5×5

= 3/(5^2)(2^0)

as the denominator is in the form of 5^m×2^n it has terminating decimal expansion.

= 3(2^2)/(5^2)(2^2) .....

(multiplying by 2^2 in denominator as well as numerator)

= 3×4/ 10^2 ..... [(x^a)(y^a)= (xy)^a]

= 12/100

= 0.12
