Answer 1

Answer:

b) non terminating decimal

explanation:

The given number is 77/210 and HCF (77, 210) = 7.

77/210 : 7/7 = 11/30

Here, 11/30 is in its simplest form. 30

Now, 30 = 2 × 3 × 5 is not of the form

2m ×5n.

So, the given number has a non-terminating repeating decimal expansion.

Answer 2

Answer:

77/210 has a non terminating decimal because the denominator multiple is 2×3×5×7.
