Guidelines for Solving Exercise 2 on Page 48 of Grade 5 Math Workbook
Problem Statement:
The sum of the ages of a sister and her brother is 36. The sister is 8 years younger than the brother. Determine the age of the sister and the age of the brother.
Solution Method:
* Observations:
- The problem provides:
+ Total age of sister and brother: 36
+ Age difference: 8 years
- The problem requires: Find the ages of the sister and the brother.
* Solution Approach:
- Find the brother's age by taking the sum of their ages and subtracting the difference (brother's younger age), then divide by 2.
- Find the sister's age by adding the brother's age and the difference (age difference between them).
Answer:
Brother's age is: (36 - 8) : 2 = 14 (years)
Sister's age is: 14 + 8 = 22 (years)
Final Answer: Sister is 22 years old, brother is 14 years old.
