Question

Classify the following statement as true or false:

$\frac{\mathbf{4}}{\mathbf{21}}$ can be represented as non-terminating repeating decimal.

• A. True
• B. False

Answer 1

The correct option is A True

Prime factorization of the denominator is $21=3\times 7$

As we can see the denominator is having prime factors other than $2$ or $5$ so it is a non-terminating decimal.
