Answer 1

Answer:

123

Step-by-step explanation:

Answer 2

Answer:

The required sum of the period and periodicity of the given number is: 126.

Step-by-step explanation:

• The number of recurring digits in a recurring decimal number after the decimal point is known as the periodicity of recurring decimals. Or, the amount of digits in a period of a recurring decimal is the periodicity.
• The decimal period of a circulating decimal is the number of digits that repeat. Any non-regular fraction or recurring decimal is periodic and has decimal period which is independent of length of the decimal.
• In the given number, as the bar is used above 123, So, 123 keeps on recurring. Hence, the period of the number will be 123 with its periodicity being 3. Thus, their sum will be: 126.
