Answer 1

1/11  2/12  3/11 4/11  5/11 6/11  7/11  8/11 9/11  10/11

10/1 10/2 10/3 10/4 10/5  10\6  10/7 10/8  10/9 10/10

7/5  >  2/5
6/ 8 > 6/9
6/8  <  6/4
4/5 >  2/3

Answer 2

1) чисельник-2,3,4,5,6,7,8,9,10
2) знаменник- 2,3,4,5,6,7,8,9
4) перва дробь: чисельник 5,знаменник 7. Вторая:чисельник 6,знаменник 7. Вторая дробь больше. И так следующие два примера

Answer 3

Examples of Fraction Comparisons

# Comparing Fractions with Equal Denominators

1. Comparison 1: Comparing fractions with equal denominators: - 3/8 vs. 5/8 - Solution: Since the denominators are the same, we compare the numerators. 5/8 is greater than 3/8.

2. Comparison 2: Comparing fractions with equal denominators: - 2/5 vs. 4/5 - Solution: With the same denominator, we compare the numerators. 4/5 is greater than 2/5.

3. Comparison 3: Comparing fractions with equal denominators: - 1/6 vs. 3/6 - Solution: The denominators are equal, so we compare the numerators. 3/6 is greater than 1/6.

# Comparing Fractions with Equal Numerators

1. Comparison 1: Comparing fractions with equal numerators: - 3/7 vs. 3/9 - Solution: Since the numerators are the same, we compare the denominators. 3/7 is greater than 3/9.

2. Comparison 2: Comparing fractions with equal numerators: - 4/8 vs. 4/12 - Solution: With the same numerator, we compare the denominators. 4/8 is greater than 4/12.

3. Comparison 3: Comparing fractions with equal numerators: - 5/11 vs. 5/15 - Solution: The numerators are equal, so we compare the denominators. 5/11 is greater than 5/15.

# Comparing Proper and Improper Fractions

1. Comparison 1: Comparing proper and improper fractions: - 2/3 vs. 7/2 - Solution: We convert the improper fraction to a mixed number. 2/3 is less than 3 1/2.

2. Comparison 2: Comparing proper and improper fractions: - 5/4 vs. 9/2 - Solution: Converting the improper fraction to a mixed number, 5/4 is less than 4 1/2.

3. Comparison 3: Comparing proper and improper fractions: - 3/5 vs. 8/3 - Solution: Converting the improper fraction to a mixed number, 3/5 is less than 2 2/3.

# Comparing Fractions with Different Denominators

1. Comparison 1: Comparing fractions with different denominators: - 2/5 vs. 3/8 - Solution: Find a common denominator. Converting both fractions to have a denominator of 40, we get 16/40 vs. 15/40. Therefore, 2/5 is greater than 3/8.

2. Comparison 2: Comparing fractions with different denominators: - 3/7 vs. 5/9 - Solution: Finding a common denominator, we convert both fractions to have a denominator of 63. This gives us 27/63 vs. 35/63. Therefore, 3/7 is less than 5/9.

3. Comparison 3: Comparing fractions with different denominators: - 4/11 vs.
