Comparing Fractions

Let's compare the given fractions:

1. 5/12 and 3/7: - To compare these fractions, we can find a common denominator and then compare the numerators. - The common denominator for 12 and 7 is 84. - Converting 5/12 to have a denominator of 84 gives us 35/84, and 3/7 becomes 36/84. - Therefore, 5/12 < 3/7.

2. 9/14 and 13/21: - Again, we can find a common denominator to compare these fractions. - The common denominator for 14 and 21 is 42. - Converting 9/14 to have a denominator of 42 gives us 27/42, and 13/21 becomes 26/42. - Therefore, 9/14 > 13/21.

3. 20/23 and 2/3: - Comparing these fractions, we can see that the denominators are different. - To compare them, we can convert 2/3 to have a denominator of 23, which gives us 15.33/23. - Therefore, 20/23 > 2/3.

4. 3/24 and 7/16: - We can simplify these fractions to make the comparison easier. - 3/24 simplifies to 1/8, and 7/16 simplifies to 7/16. - Therefore, 3/24 < 7/16.

In summary: - 5/12 < 3/7 - 9/14 > 13/21 - 20/23 > 2/3 - 3/24 < 7/16
