1. B 2. C 3. D 4. A 5. The question for part 5 is incomplete and cannot be answered.

To find the largest rational number, we compare the given fractions by converting them to decimals or finding a common denominator. For the inequalities, we compare the fractions directly or convert them to decimals to determine which inequality is true. To find the smallest rational number, we convert all options to decimals and compare their values. To determine which numbers are smaller than 3/7, we convert the given numbers to decimals and compare them with the decimal equivalent of 3/7.
