Answer 1

it is a non terminating decimal expansion bcoz for terminating decimal expansion the denominator should be in the 2ki power m and 5 ki power n

Answer 2

Answer:

Terminating Decimal Expansion

Step-by-step explanation:

Any fraction in the lowest form with denominator in the form

${2}^{x} \times {5}^{y}$

is terminating. If denominator has any other factor, it is Non-Terminating. Here 441 = 7x7x9.

$\frac{441}{ {2}^{2} \times {5}^{7} \times {7}^{2} } = \frac{7 \times 7 \times 9}{2 \times 2 \times {5}^{7} \times 7 \times 7 } = \frac{9}{2 \times 2 \times {5}^{7} }$

So, the given fraction has a terminating decimal expansion.
