3.Without actually performing the long division , state whether the rational numbers (i) 427/625 (ii) 619/ 325 will have terminating decimal expansion or non- terminating repeating decimal expansion.

(i) In 427/625, 625 can be expressed as 2⁰×5³​. Therefore, 427/625 has a terminating decimal expansion.
(ii) In 619/325, 325 cannot be expressed as 2^m×5ⁿ. So, 619/325 has a non-terminating decimal expansion.

I hope you understood.
