1/4 Part of a day is 6 hours.

2. 3/5- 7/25=
Like fraction of 3/5 is 3/5×5/5=15/25

3/5 – 7/25 = 15/25-7/25=8/25

2/5 = 2/5×4/4=8/20
6/10 = 6/10×2/2 = 12/20
Descending order is12/20,8/20,4/20.
i.e. 6/( 10) ,2/5, 4/20

4. Distance jogged in the morning = 3/5 km

Distance jogged in the evening = 2/15 km
Total distance jogged in one day = 3/5+ 2/15 = 9/15 + 2/15 = 11/15 km

Fraction is6/( 14).

8. a) 1 – 3/5 = 5/5 – 3/5 = 2/5

b) 3 – 9/5 = 15/5 – 9/(5 ) = 6/5

9. Part of cake given to his sister = 3/8

Part of cake given to his friend = 2/8
Total parts = 3/8+2/8= 5/8
