10. How many minutes are there in 1/3 of an hour?
Answers:
1. 30
2. 50 paise
3. 2/3
4. ¼
5. Total number of parts = 8
Number of parts given to his sister and his friends = 2 + 3 = 5
Fraction of the cake consumed = 5/8
6. Total number of chocolates in Anu’s hand = 15
Number of chocolates given to his friends = 2/5 of 15
= 2/5 x 15 = 30 / 5 = 6 chocolates
Number of chocolates remaining = 15 – 6 = 9 chocolates
7. a) One fourth of 36 = ¼ x 36 = 36 / 4 = 9
b) Two third of 24 = 2/3 x24 = 48 / 3 = 16
8. Cost of 1 kg apple = Rs 240
Cost of ¼ kg apple = ¼ x 240 = 240/4 = 60 rupees.
Cost of 1 ¼ kg apple = 240 + 60 = 300 rupees
9. Equivalent fractions of ¼ are ¼, 2/8, 3/12, 4/16.
10. 1/3 of an hour = 1/3 x 60 minutes
= 60/3 = 20 minutes
