If the answer is recurring, put a dot after the recurring number. (Example, if the answer is 1.5666, put the answer as => 1.56. )

To express a recurring decimal using a dot to indicate the repeating part, follow these guidelines:

1. Identify the Recurring Part: Determine which digits in the decimal representation repeat indefinitely.
2. Format the Number: Use the dot notation to highlight the recurring digits, placing a dot directly after the last digit of the repeating sequence.

For example, if the decimal is 1.566666..., you would observe that the digit '6' keeps repeating. Therefore, you denote this with a dot:

Final Representation: 1.56

This notation helps to succinctly communicate that, beyond the shown digits, the '6' continues indefinitely. If there are further complexities or specific examples you'd like assistance with, feel free to ask!
