Answer 2

Comparing Fractions

Let's compare the given fractions:

1. 4/7 and 7/30: To compare these fractions, we can find a common denominator. The least common multiple (LCM) of 7 and 30 is 210. Converting both fractions to have a denominator of 210, we get: - 4/7 = 60/210 - 7/30 = 49/210

Since 60/210 is greater than 49/210, we can conclude that 4/7 is greater than 7/30.

2. 5/6 and 1/6: Both fractions have the same denominator, so we can compare their numerators directly. Since 5 is greater than 1, we can conclude that 5/6 is greater than 1/6.

3. 9/8 and 1/7: To compare these fractions, we need to find a common denominator. The LCM of 8 and 7 is 56. Converting both fractions to have a denominator of 56, we get: - 9/8 = 63/56 - 1/7 = 8/56

Since 63/56 is greater than 8/56, we can conclude that 9/8 is greater than 1/7.

4. 72/72 and 1.8: The fraction 72/72 is equal to 1, so we can compare it directly with 1.8. Since 1 is less than 1.8, we can conclude that 72/72 is less than 1.8.

5. 19/19 and 49/49: Both fractions have the same numerator and denominator, so they are equal. We can conclude that 19/19 is equal to 49/49.

6. 11/12 and 12/11: To compare these fractions, we can find a common denominator. The LCM of 12 and 11 is 132. Converting both fractions to have a denominator of 132, we get: - 11/12 = 121/132 - 12/11 = 144/132

Since 121/132 is less than 144/132, we can conclude that 11/12 is less than 12/11.

I hope this helps! Let me know if you have any further questions.
