Question

Has the rational no. 441÷2^2 ×5^7×7^2 a terminating or non - terminating decimal representation ?​

Answer 1

ans : 441 / ( 2^2  *  5^7  * 7^2 )

= ( 3^2  *  7^2 ) / ( 2^2 * 5^7 * 7^2 )

= 3^2 / ( 2^2  *  5^7 )

explanation :Since the denominator of this rational number is in the form of 2^ m * 5^n,so it will have terminating decimal representation

Answer 2

Answer:

terminating (422050781.25)

Explanation:

the deno is 2^3×7^2×5

since it has 7 in deno and not in the form of 2^m ×5^n and the numerator ha 441=7×7×3×3

when we simplify it we get 3^2 by 2^3×5

hence it is a terminating decimal
