Question 6: The following fractions represent just three different numbers. Separate them into three groups of equivalent fractions, by changing each one to its simplest form.
Question 7: Find answers to the following. Write and indicate how you solved them.
[∴ L.C.M. of 9 and 5 is 45]
[∴ L.C.M. of 16 and 9 is 144]
[∴ L.C.M. of 5 and 20 is 100]
[∴ L.C.M. of 15 and 30 is 30]
Question 8: Ila read 25 pages of a book containing 100 pages. Lalita read 2/5 of the same book. Who reads less?
Ila read 25 pages out of 100 pages.
Fraction of reading the pages = 25/100 = 1/4 th part of the book
Lalita read 2/5 th part of the book = 40/100 pages
Therefore, Ila read less.
Question 9: Rafiq exercised for 3/6 of an hour, while Rohit exercised for 3/4of an hour. Who exercised for a longer time?
Rafiq exercised 3/6 of an hour.
Rohit exercised 3/4 of an hour.
Therefore, Rohit exercised for a longer time.
Question 10: In class A of 25 students, 20 passed in first class; in another class B of 30 students, 24 passed in first class. In which class was a greater fraction of students getting first class?
In class A, 20 passed out of 25, i.e., 20/25 = 4/5
In class B, 24 passed out of 30, i.e., 24/30 = 4/5
Hence, each class have the same fraction of student getting a first class.
Question 1: Write these fractions appropriately as additions or subtractions:
Question 2: Solve:
Question 3: Shubham painted 2/3of the wall space in his room. His sister Madhavi helped and painted 1/3 of the wall space. How much did they paint together?
Fraction of wall painted by Shubham = 2/3
Fraction of wall painted by Madhavi = 1/3
Total painting by both of them =
Therefore, they painted the complete wall.
Question 4: Fill in the missing fractions.
Question 5: Javed was given a basket of oranges. What fraction of oranges was left in the basket?
Total = 1
Fraction of Orange left
Thus, 2/7 oranges were left in the basket.
Question 1: Solve
(a) L.C.M. of 3 and 7 is 21
(b) L.C.M. of 10 and 15 is 30
(c) L.C.M. of 9 and 7 is 63
Question 2: Sarita bought 2/5 metre of ribbon and Lalita 3/4 metre of ribbon. What is the total length of the ribbon they bought?
Ribbon bought by Sarita = 2/5 m and Ribbon bought by Lalita = 3/4 m
The total length of ribbon =
Therefore, they bought of ribbon.
Question 3: Naina was given piece of cake and Najma was given piece of cake. Find the total amount of cake was given to both of them.
Cake taken by Naina = piece and Cake taken by Najma piece
Total cake taken
Therefore, the total consumption of cake is
Question 4: Fill in the boxes:
Question 5: Complete the addition-subtraction box.
Question 6: A piece of wire 7/8 metre long broke into two pieces. One piece was 1/4 metre long. How long is the other piece?
The total length of wire = 7/8 meter
Length of first part = 1/4 meter
Remaining part [∴ L.C.M. of 8 and 4 is 8]
Therefore, the length of the remaining part is 5/8 meter.
Question 7: Nandini’s house is 9/10 km from her school. She walked some distance and then took a bus for 1/2 km to reach the school. How far did she walk?
The total distance between school and house 9/10 km
Distance covered by bus = 1/2 km
Remaining distance [∴ L.C.M. of 10 and 2 is 10]
Therefore, the distance covered by walking is 2/5 km.
Question 8: Asha and Samuel have bookshelves of the same size partly filled with books. Asha’s shelf is 5/6 th full and Samuel’s shelf is 2/5 th full. Whose bookshelf is more full? By what fraction?
⇒ [∴ L.C.M. of 6 and 5 is 30]
∴ Asha’s bookshelf is more covered than Samuel.
Question 9: Jaidev takes minutes to walk across the school ground. Rahul takes 7/4 minutes to do the same. Who takes less time and by what fraction?
Time taken by Jaidev = minutes = 11/5 minutes
Time taken by Rahul = 7/4 minutes
Difference [∴ L.C.M. of 5 and 4 is 20]
Thus, Rahul takes less time, which is 9/20 minutes.
