Find the rational numbers represented by each of the question marks marked on the following number lines.

If \(\frac { 3 }{ 4 } \) of a box of apples weighs 3 kg and 225 gm, how much does a full box of apples weight?

In a map, if 1 inch refers to 120 km, then find the distance between two cities B and C which are \(4\frac { 1 }{ 6 } \) inches and \(3\frac { 1 }{ 3 } \) inches from the city A which is in between the cities B and C.

If \(\frac { 1 }{ 4 } \) of a ragi adai weighs 120 grams, what will be the weight of \(\frac { 2 }{ 3 } \) of the same ragi adai?

Divide \(\frac{7}{36}\) by \(\frac{35}{81}\)

Explain why the statements are true?
1.4>\(\frac{1}{4}\)

The pairs are equivalent rational numbers?
\(\frac { -6 }{ 4 } ,\frac { 33 }{ -22 } \)

Are there any rational numbers between \(\frac{-7}{11}\) and \(\frac{6}{-11}?\)

Is \(\frac { 3 }{ 5 } -\frac { 7 }{ 8 } =\frac { 7 }{ 8 } -\frac { 3 }{ 5 } \)So, what do you conclude ?

Observe that, \(\frac { 1 }{ 1.2 } +\frac { 1 }{ 2.3 } =\frac { 2 }{ 3 } ;\frac { 1 }{ 1.2 } +\frac { 1 }{ 2.3 } +\frac { 1 }{ 3.4 } =\frac { 3 }{ 4 } ;\frac { 1 }{ 1.2 } +\frac { 1 }{ 2.3 } +\frac { 1 }{ 2.3 } +\frac { 1 }{ 3.4 } +\frac { 1 }{ 4.5 } =\frac { 4 }{ 5}\) Use your reasoning skills, to find the sum of the first 7 numbers in the pattern given above.
