Question 1 (iii)
Without actually performing the long division, state whether 64455 will have a terminating decimal expansion or a non-terminating repeating decimal expansion.
64455
Factorize the denominator; we get,
455=5×7×13
The denominator is not in the form of 2m×5n, as there are other prime factors as well.
Hence, the decimal expansion of the given number is recurring (repeating).
