Guidelines for solving Grade 5 Mathematics on pages 148, 149 (including solution methods)
1. Solving Exercise 1 - Grade 5 Mathematics on pages 148, 149
Solution Method:
a) The main colored part represents the numerator; the denominator is the total of both the colored and uncolored parts.
b) Improper fractions are individual leftover shapes after coloring; the numerator is the colored part in each shape with a division; the denominator is the total of colored and uncolored parts in the divided shape.
Solution Method:
- Step 1: Mentally determine a natural number that both the numerator and denominator can be evenly divided by, greater than 1.
- Step 2: Divide both the numerator and denominator by the determined natural number.
3. Solving Exercise 3 on page 149 Grade 5 Mathematics Textbook
Solution Method:
How to find a common denominator for two fractions:
- Multiply the numerator and denominator of the first fraction by the denominator of the second fraction.
- Multiply the numerator and denominator of the second fraction by the denominator of the first fraction.
4. Solving Exercise 4 on page 149 Grade 5 Mathematics Textbook
Solution Method:
- For fractions with the same denominator: Compare the numerators of the two fractions => The fraction with the larger numerator is greater.
- For fractions with different denominators:
+ Step 1: Find a common denominator for the two fractions to make them have the same denominator.
+ Step 2: Compare the numerators of the two fractions; the fraction with the larger numerator is greater, and vice versa for the fraction with the smaller numerator.
