Comparing Fractions without a Common Denominator

When comparing fractions without a common denominator, we can follow a few steps to determine which fraction is greater or if they are equal. Let's compare the given fractions:

1. 1/20 and 1/20: - Since the numerators are the same and the denominators are the same, these fractions are equal.

2. 3/7 and 3/8: - To compare these fractions, we can cross-multiply. - Cross-multiplying means multiplying the numerator of one fraction by the denominator of the other fraction. - For 3/7 and 3/8, we have (3 * 8) and (3 * 7). - 3/7 = 24 and 3/8 = 21. - Since 24 is greater than 21, 3/7 is greater than 3/8.

3. 15/17 and 17/14: - To compare these fractions, we can also cross-multiply. - For 15/17 and 17/14, we have (15 * 14) and (17 * 17). - 15/17 = 210 and 17/14 = 289. - Since 210 is less than 289, 15/17 is less than 17/14.

In summary: - 1/20 is equal to 1/20. - 3/7 is greater than 3/8. - 15/17 is less than 17/14.
