Which of the following decimal expansion are rational. If they are rational `p/q` then write down the prime factors of q.
`11.21sqrt(478)`

Write the simplest rationalizing factor of sqrt(27)

the decimal expansion of some real number are given below. In each case, decide whether they are rational or not. If they are rational, write in in the form p/q what can you say about the prime factors of q 0.overline(16)

The following real numbers have decimal expansions as given below. In each case, decide whether they are rational or not. If they are rational, and of the form p/q , what can you say about the prime factors of q? (i)43. 123456789 (ii) 0. 1201

Assertion : 29/9261 will have a non-terminating repeating decimal expansion. Reason : Let a = p/q be a rational number such that p and q are co-prime and the prime factorisation of q is of the form 2^(n)xx5^(m) where n and m are non-negative integers (whole numbers). Then a has a decimal expansion, which is non-terminating repeating.

Which of the following rational numbers have non-terminating repeating decimal expansion?
