Comparing Fractions

Sure! Let's compare the given fractions:

1) 5/12 and 5/7: To compare these fractions, we can find a common denominator and then compare the numerators. The least common multiple (LCM) of 12 and 7 is 84. Converting both fractions to have a denominator of 84, we get: - 5/12 = 35/84 - 5/7 = 60/84

Since the numerators are different, we can directly compare the fractions. In this case, 5/7 is greater than 5/12.

2) 6/23 and 9/23: Since the denominators are the same, we can directly compare the numerators. In this case, 9/23 is greater than 6/23.

3) 8/9 and 17/18: To compare these fractions, we can find a common denominator and then compare the numerators. The least common multiple (LCM) of 9 and 18 is 18. Converting both fractions to have a denominator of 18, we get: - 8/9 = 16/18 - 17/18 = 17/18

Since the numerators are different, we can directly compare the fractions. In this case, 17/18 is greater than 8/9.

4) 6/7 and 17/21: To compare these fractions, we can find a common denominator and then compare the numerators. The least common multiple (LCM) of 7 and 21 is 21. Converting both fractions to have a denominator of 21, we get: - 6/7 = 18/21 - 17/21 = 17/21

Since the numerators are different, we can directly compare the fractions. In this case, 17/21 is greater than 6/7.

5) 7/12 and 11/15: To compare these fractions, we can find a common denominator and then compare the numerators. The least common multiple (LCM) of 12 and 15 is 60. Converting both fractions to have a denominator of 60, we get: - 7/12 = 35/60 - 11/15 = 44/60

Since the numerators are different, we can directly compare the fractions. In this case, 11/15 is greater than 7/12.

6) 5/9 and 4/7: To compare these fractions, we can find a common denominator and then compare the numerators. The least common multiple (LCM) of 9 and 7 is 63. Converting both fractions to have a denominator of 63, we get: - 5/9 = 35/63 - 4/7 = 36/63

Since the numerators are different, we can directly compare the fractions. In this case, 4/7 is greater than 5/9.
