Question 1: Write the following in decimal form and say what kind of decimal expansion each has:

(i) (36)/(100)

Answer: Decimal expression of the given question is equal to 0.36
This is terminating number.

Thus, it is non-terminating repeating number

Hence, it is terminating number

Hence, it is non-terminating repeating number

Hence, it is non-terminating repeating number

Asnwer:

Hence, it is terminating number

Question 2: You know that . Can you predict what the decimal expansions of are, without actually doing the long division? If so, how? [Hint : Study the remainders while finding the value of 1/ 7 carefully.]
