What can you say about the prime factorizations of the denominators of the following rational?

(i) 43.123456789

(ii)

(iii)

(iv) 0.120120012000120000…

(i) 43.123456789 = =

Since Prime factorization of the denominator is in the form, where m, n are non-negative integers.

(ii) Since has non-terminating repeating decimal expression, therefore Prime factorization of the denominator contains factors other than 2 or 5.

(iii) Since has non-terminating repeating decimal expression, therefore Prime factorization of the denominator contains factors other than 2 or 5.

(iv) Since has non-terminating repeating decimal expression, therefore Prime factorization of the denominator contains factors other than 2 or 5.
