Hey Gayatri,

Thank you for reaching out!

In this case, the use of parentheses denotes a periodic number. That is, the sequence of numbers inside the parenteses is repeating forever.

As an example, the fraction 1/3 equals 0.3(3) which is the same as 0.333... As another example, take the fraction 1/11 which equals 0.090909... Using the parentheses notation, this decimal number can be shorthanded to 0.(09).

Hope this helps!

Kind regards,
