Shade the rectangle for the given pair of fractions and say which is greater among them.
(i) \(\cfrac { 1 }{ 3 } and\cfrac { 1 }{ 5 } \)

(ii) \(\cfrac { 2 }{ 5 } and\cfrac { 5 }{ 8 } \)

Arrange the fractions in ascending order.\(\cfrac { 3 }{ 5 } ,\cfrac { 9 }{ 10 } ,\cfrac { 11 }{ 15 } \)

Arrange the fractions in descending order \(\cfrac { 9 }{ 20 } ,\cfrac { 3 }{ 4 } ,\cfrac { 7 }{ 12 } \)
(i) \(\cfrac { 2 }{ 3 } +\cfrac { 5 }{ 7 } \)
(ii) \(\cfrac { 3 }{ 5 } -\cfrac { 3 }{ 8 } \)
