Guide to Solve Exercise 3 Page 76 Math Book Grade 4
Problem Statement:
Class 4A has 32 students divided into groups, each group has 4 students. Class 4B has 28 students also divided into groups, each group has 4 students. How many groups in total?
Solution Method:
You can solve this problem in 2 ways:
- Method 1:
+ Step 1: Calculate the number of student groups in class 4A by dividing the total number of students in class 4A by the number of students per group.
+ Step 2: Similarly, calculate the number of student groups in class 4B by dividing the total number of students in class 4B by the number of students per group.
+ Step 3: Calculate the total number of student groups in both classes 4A and 4B by adding the results from step 1 to the results from step 2.
- Method 2:
+ Calculate the total number of students in both classes by adding the number of students in class 4A to the number of students in class 4B.
+ Calculate the number of student groups in both classes by dividing the total number of students in both classes by the number of students per group.
Answer:
Method 1:
The number of student groups in class 4A is:
32 : 4 = 8 (groups)
The number of student groups in class 4B is:
28 : 4 = 7 (groups)
The number of student groups in both classes 4A and 4B is:
8 + 7 = 15 (groups)
Method 2:
Both classes have a total of:
32 + 28 = 60 (students)
The number of student groups in both classes 4A and 4B is:
60 : 4 = 15 (groups)
Final answer: 15 groups.
