Q3Which of the following fractions is a terminating decimal?
(I) 49
(II) 65
(III) 611


A. Only (I)
B. Only (II)
C. Both (I) and (III)
D. Both (II) and (III)

Step: 1
A fraction can be converted into a decimal by dividing the numerator by the denominator. If the division ends with a remainder of zero, the decimal is called a terminating decimal.
Step: 2
Consider the first fraction, 49 :
49 = 0.44444444...
  [Convert the fraction into a decimal number.]
Step: 3
Consider the second fraction, 65 :
65 = 1.20
  [Convert the fraction into a decimal number.]
Step: 4
Consider the third fraction, 611:
611= 0.54545454...
  [Convert the fraction into a decimal number.]
Step: 5
Among the fractions, the second fraction is a terminating decimal.
Correct Answer is :   Only (II)
Q4Which of the following is a repeating decimal?
i. 33 ÷ 6
ii.6 ÷ 33

A. (ii)
B. (i)
C. Both (i) and (ii)
D. None of the above

Step: 1
33 ÷ 6
  [Divide 33 with 6.]

Step: 2
The quotient obtained after dividing 33 with 6 is 5.5, which is a terminating decimal.
Step: 3
6 ÷ 33
  [Divide 6 with 33.]
Step: 4
After dividing 6 with 33, the quotient obtained is 0.181818...
Step: 5
Since 18 is coming repetatively in quotient, 6 ÷ 33 is a repeating decimal.
Step: 6
So, (ii) is a repeating decimal.
Correct Answer is :   (ii)
