Q1: Without counting one by one, find the total number of pens. Write one multiplication sentence. Ans: There are 4 boxes with 5 pens in each box.
5 + 5 + 5 + 5 = 20
So, the multiplication sentence is 4 × 5 = 20 pens.
Q2: A student wrote 5 + 5 + 5 + 5 + 5 = 25 for the given picture. Is this correct? Write the correct repeated addition and multiplication sentence.Ans: This is not correct because 5 shows the number of bags, not the number of apples in each bag.
If each bag has 3 apples, the repeated addition is:
3 + 3 + 3 + 3 + 3 = 15
So, the correct multiplication sentence is 5 × 3 = 15.
Q3: Each decorative band needs 5 beads. How many beads are needed to make 9 such bands? Ans: One band uses 5 beads.
For 9 bands: 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 45
So, the multiplication sentence is 9 × 5 = 45 beads.
Q4: If 28 biscuits are packed equally with 7 biscuits in each box, how many boxes will be needed? Ans: There are 28 biscuits in total.
28 ÷ 7 = 4

Q5: 20 mangoes are shared equally among 4 children. How many mangoes will each child get? Will any mangoes be left?Ans: 20 mangoes are shared among 4 children.
20 ÷ 4 = 5
Each child will get 5 mangoes and no mango will be left.
Q6: The items in the picture are meant to be shared equally. Is the sharing correct? Give one reason.
Ans: No, the sharing is not correct.
This is because all the plates do not have the same number of items, so the sharing is not equal.
Q7: Four children are sitting in each row. There are 6 such rows. How many children are there in total? Write one multiplication sentence.
Ans: There are 6 rows and each row has 4 children.
So, repeated addition is 4 + 4 + 4 + 4 + 4 + 4 = 24.
The multiplication sentence is 6 × 4 = 24 children.
Q8: Complete the number pattern and name the multiplication table it belongs to.Ans: The completed pattern is 5, 10, 15, 20, 25.
This pattern belongs to the 5 times table.
Q9: There are 32 legs in total. How many stools are there? Which operation will you use?Ans: Each stool has 4 legs.
32 ÷ 4 = 8
So, there are 8 stools.
Division is used because the total number of legs is divided into equal groups of 4.
Q10: Rina says that 6 × 4 and 4 × 6 give the same answer. Is she correct? Explain your answer.
Ans: Yes, Rina is correct.
6 × 4 means 6 groups of 4 and 4 × 6 means 4 groups of 6.
Both give the same total, which is 24.
