Question

write whether the rational no 7/15 will have a terminating decimal expansion or a non terminating repeating decimal expensions

Answer 1

non yerminating because 15=3and5are the factors in that not 2 is present . 2 raise to m ×5 raise to m it is a theorem

Answer 2

Since 7/15 have 15 as its denominator and factorization of 15 is 5x3, which is not in the form of 2^m×5^n. Therefore it will have non terminating repeating decimal expansion.

I hope that my answer will help u.
Like it and give it the brainliest answer if u r satisfied from the answer. Thank you!!!
