Exercise 7.6

Question 1.
Solve


Solution:





Question 2.
Sarita bought \(\frac { 2 }{ 5 }\) metre of ribbon and Lalita \(\frac { 3 }{ 4 }\) metre of ribbon. What is the total length of the ribbon they bought?
Solution:
Length of ribbon bought by Sarita = \(\frac { 2 }{ 5 }\) metre
Length of ribbon bought by Lalita = \(\frac { 3 }{ 4 }\) metre
∴ Length of ribbon bought by Sarita and Lalita

Hence, the required length = \(\frac { 23 }{ 20 }\) metre

Question 3.
Naina was given 1\(\frac { 1 }{ 2 }\) piece of cake and Najma was given 1\(\frac { 1 }{ 3 }\) piece of cake. Find the total amount of cake was given to both of them.
Solution:
Piece of cake given to Naina = 1\(\frac 1{ 1 }{ 2 }\)
Piece of cake given to Najma = 1\(\frac 1{ 1 }{ 3 }\)
Piece of cake given to Naina and Najma

Hence the total amount of piece given to both = 2\(\frac { 5 }{ 6 }\).

Question 4.
Fill in the boxes:

Solution:

Here, missing number is \(\frac { 1 }{ 4 }\) more than \(\frac { 5 }{ 8 }\) .


Here, missing number is \(\frac { 1 }{ 2 }\) more than \(\frac { 1 }{ 5 }\) .

Here, missing number is \(\frac { 1 }{ 6 }\) less than \(\frac { 1 }{ 2 }\).

Question 5.
Complete the addition-subtraction box.

Solution:

Thus the box may be completed as follows:

Question 6.
A piece of wire \(\frac { 7 }{ 8 }\) metre long broke into two pieces. One piece was \(\frac { 1 }{ 4 }\) metre long. How long is the other piece?
Solution:
Total length of the wire = \(\frac { 7 }{ 8 }\) metre
Length of one piece of wire = \(\frac { 1 }{ 4 }\) metre
∴ Length of the other piece = \(\frac { 7 }{ 8 }\) – \(\frac { 1 }{ 4 }\)
LCM of 8 and 4 = 8

Hence, the length of the other piece = \(\frac { 5 }{ 8 }\) metre.

Question 7.
Nandini’s house is \(\frac { 9 }{ 10 }\) km from her school. She walked some distance and then took a bus for \(\frac { 1 }{ 2 }\)km to reach the school. How far did she walk?
Solution:
Total distance from house to school = \(\frac { 9 }{ 10 }\) km.
Distance travelled by Nandini by bus = \(\frac { 1 }{ 2 }\) km
∴ Distance travelled by her on foot

Hence, the distance travelled by her on foot = \(\frac { 2 }{ 5 }\)km.

Question 8.
Asha and Samuel have bookshelves of the same size partly filled with books. Asha’s shelf is \(\frac { 5 }{ 6 }\) th full and Samuel’s shelf is \(\frac { 2 }{ 5 }\) th full. Whose bookshelf is more full? By what fraction?
Solution:
Asha’s shelf is \(\frac { 5 }{ 6 }\) th full
and Samuel’s shelf is \(\frac { 2 }{ 5 }\) th full
Comparing \(\frac { 5 }{ 6 }\) and \(\frac { 2 }{ 5 }\)
LCM of 6 and 5 = 30

Hence, Asha’s shelf is full more than Samuel’s shelf.

Hence, \(\frac { 13 }{ 30 }\) th fraction is more full of Asha’s shelf.

Question 9.
Jaidev takes 2\(\frac { 1 }{ 5 }\) minutes to walk across the school ground. Rahul takes \(\frac { 7 }{ 4 }\) minutes to do the same. Who takes less time and by what fraction?
Solution:
Jaidev takes 2\(\frac { 1 }{ 5 }\) minutes 5
Rahul takes 2\(\frac { 7 }{ 4 }\) minutes
Comparing 2\(\frac { 1 }{ 5 }\) minutes and \(\frac { 7 }{ 4 }\) minutes


So, the time take to cover the same distance by Rahul is less than that of Jaidev.

Hence, Rahul takes \(\frac { 9 }{ 20 }\) minutes less to across the school ground.
