Question

which of the following is terminating and non terminating:- 1.-627/300 2.85/300 3.39/160

Answer 1

Answer:

sry if the answer is wrong

Step-by-step explanation:

ANSWER

We know that the divisor of the forms 2

n

5

m

always form a terminating decimal number. Let us simplify the expressions and find if the expansion have a terminating decimal expansion.

Option A :

210

77

=

2×3×5×7

7×11

=

2×3×5

11

Since there is a factor of 3 in the denominator, the decimal expansion will not be terminating.

Option B :

30

23

=

2×3×5

23

Since, the denominator contains a power of 3 , it is non-terminating.

Option C :

441

125

=

3×3×7×7

5×5×5

This is also non-terminating.

Option D :

8

23

=

2×2×2

23

This contains power of 2 in the denominator. Hence, the decimal expansion is terminating.
