1. Exercise 1 on page 122
Problem Statement:
Comparing two fractions:
Solution Method:
Comparing fractions with different denominators:
- Step 1: Make the denominators the same for both fractions
- Step 2: Compare the numerators of the new fractions as you would compare regular whole numbers => The fraction with the greater numerator is larger.
- Step 3: Draw a conclusion.
Answer:
2. Exercise 2 on page 122 Comparing two fractions with different denominators
Problem Statement:
Simplify then compare two fractions:
Solution Method:
- Step 1: Simplify the fractions that are not already simplified
- Step 2: When the simplified fractions have the same denominator as the given fraction, compare their numerators. The fraction with the greater numerator is larger, and vice versa
- Step 3: Draw a conclusion.
Answer:
3. Grade 4 Math Comparing two fractions with different denominators page 122 - Exercise 3
Problem Statement:
Solution Method:
- To determine who ate more cakes between Mai and Hoa, we compare the number of cakes each ate, or in other words, compare 3/8 and 2/5.
- Because the two fractions have different denominators => We find a common denominator to make them have the same denominator, then compare the numerators. The fraction with the greater numerator is larger.
