Comparing Fractions

Let's compare the following fractions:

1. 3/7 and 1 1/7 2. 1 1/2 and 11/12 3. 12/17 and 17/12 4. 6/7 and 4/3

1. Comparing 3/7 and 1 1/7

To compare 3/7 and 1 1/7, we need to find a common denominator. The common denominator for 7 and 1 is 7.

Converting 1 1/7 to an improper fraction: 1 1/7 = (7 * 1 + 1) / 7 = 8/7

Now, we can compare the fractions: 3/7 < 8/7

Therefore, 3/7 is less than 1 1/7.

2. Comparing 1 1/2 and 11/12

To compare 1 1/2 and 11/12, we need to find a common denominator. The common denominator for 2 and 12 is 12.

Converting 1 1/2 to an improper fraction: 1 1/2 = (2 * 1 + 1) / 2 = 3/2

Now, we can compare the fractions: 3/2 > 11/12

Therefore, 1 1/2 is greater than 11/12.

3. Comparing 12/17 and 17/12

To compare 12/17 and 17/12, we don't need to find a common denominator because the denominators are already different.

Comparing the fractions directly: 12/17 < 17/12

Therefore, 12/17 is less than 17/12.

4. Comparing 6/7 and 4/3

To compare 6/7 and 4/3, we need to find a common denominator. The common denominator for 7 and 3 is 21.

Converting 6/7 to an equivalent fraction with a denominator of 21: 6/7 = (3 * 6) / (3 * 7) = 18/21

Converting 4/3 to an equivalent fraction with a denominator of 21: 4/3 = (7 * 4) / (7 * 3) = 28/21

Now, we can compare the fractions: 18/21 < 28/21

Therefore, 6/7 is less than 4/3.

In summary: - 3/7 is less than 1 1/7 - 1 1/2 is greater than 11/12 - 12/17 is less than 17/12 - 6/7 is less than 4/3
