Check by multiplication: There are 2 groups of 4.
2 × 4 = 8
Complete the following.
Question 1.
a.
How many groups?
12 ÷ 3 = _________
There are __________ groups.
Check: ___________
Answer: 12 ÷ 3 = 4.
There are 4 groups.
Check: 4 x 3 = 12
There are 4 groups of 3 squares.
Explanation: Given the figures with a group of squares.
The total number of squares is 12.
Each group has 3 squares.
Now, we will find out a number of groups.
So, the values are 12 ÷ 3,
Therefore, there are 4 groups of squares.
b.
How many in each group?
12 ÷ 4 = _________
There are ______ 
in each group.
Check: ______________
Answer: There are 3 squares in each group.
Check: 12 ÷ 4 = 3
So, there are 3 squares in each group.
Explanation: Given the figures with a group of squares.
The total number of squares is 12.
The total number of groups is 4.
Now, we will find out the number of squares in each group.
So, the values are 12 ÷ 4,
Thus, each group has 3 squares.
Question 2.
a. 20 As in all.
_________ As in each group.
How many groups?
20 ÷ 4 = ___________
There are ____________ groups.
Check: ____________
Answer: 4 A’s in each group.
20 ÷ 4 = 5
There are 5 groups.
Check: 4 x 5 = 20
So, all A’s are 20.
Explanation: Given the figure with 20 A’s.
There are total 20 A’s.
Each group has 4 A’s.
Now, we will find out the number of groups.
So, the values are 20, 4
i.e., 20/4
Hence, the number of groups is 5 groups.
b. 20 As in all.
_________ groups of As.
How many in each groups?
20 ÷ 5 = ___________
There are ____________ As in each group.
Check: ____________
Answer: 5 groups of A’s.
20 ÷ 5 = 4.
There are 4 A’s in each group.
Check: 4 x 5 = 20.
It means overall A’s is 20.
Explanation: Given the figure with 20 A’s.
There are total 20 A’s.
The total number of groups is 5.
Now, we will find out the number of A’s in each group.
So, the values are 20, 5
i.e., 20/5
Therefore, each group has 4 A’s.
Question 3.
a. __________ Fs in all.
_________ Fs in each group.
How many groups?
12 ÷ 2 = ___________
There are ____________ groups.
Check: ____________
Answer: 12 F’s in all.
2 F’s in each group.
12 ÷ 2 = 6.
There are 6 groups.
Chcek: 6 x 2 = 12.
So, it is correct. The overall F’s is 12.
Explanation: Given the Figure with F’s.
There are 12 F’s.
Each group has 2 F’s.
Now, we will find out number of groups.
So, the values are 12,2
i.e., 12 /2
Hence, the number of groups is 6.
b. ___________ Fs in all.
_________ groups of Fs.
How many in each groups?
12 ÷ 6 = ___________
There are ____________ Fs in each group.
Check: ____________
Answer: 12 F’s in all.
6 groups of F’s.
12 ÷ 6 = 2.
There are 2 F’s in each group.
Chcek: 6 x 2 = 12.
So, it is correct. Because the overall F’s is 12.
Explanation: Given the Figure with F’s.
There are 12 F’s.
The number of F’s groups is 6.
Now, we will find out number of F’s in each group.
So, the given values are 12,6
i.e., 12 /6
Thus, the number of F’s in each group is 2.
