1. Convert $$2 \frac{1}{4}$$ to an improper fraction:
   $$
   2 \frac{1}{4} = \frac{2 \times 4 + 1}{4} = \frac{9}{4}
   $$
   Divide by $$\frac{3}{4}$$:
   $$
   \frac{9}{4} \div \frac{3}{4} = \frac{9}{4} \times \frac{4}{3} = \frac{9 \times 4}{4 \times 3} = \frac{36}{12} = 3
   $$

2. Convert $$3 \frac{2}{5}$$ to an improper fraction:
   $$
   3 \frac{2}{5} = \frac{3 \times 5 + 2}{5} = \frac{17}{5}
   $$
   Divide by $$\frac{1}{5}$$:
   $$
   \frac{17}{5} \div \frac{1}{5} = \frac{17}{5} \times \frac{5}{1} = \frac{17 \times 5}{5 \times 1} = 17
   $$

3. Convert $$7 \frac{2}{4}$$ to an improper fraction. First note that:
   $$
   \frac{2}{4} = \frac{1}{2}
   $$
   Thus:
   $$
   7 \frac{2}{4} = 7 \frac{1}{2} = \frac{7 \times 2 + 1}{2} = \frac{15}{2}
   $$
   Note that $$\frac{5}{10} = \frac{1}{2}$$. Now divide:
   $$
   \frac{15}{2} \div \frac{1}{2} = \frac{15}{2} \times \frac{2}{1} = \frac{15 \times 2}{2 \times 1} = 15
   $$

4. Convert $$2 \frac{3}{6}$$ to an improper fraction. First note that:
   $$
   \frac{3}{6} = \frac{1}{2}
   $$
   So:
   $$
   2 \frac{3}{6} = 2 \frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{5}{2}
   $$
   Divide by $$\frac{2}{3}$$:
   $$
   \frac{5}{2} \div \frac{2}{3} = \frac{5}{2} \times \frac{3}{2} = \frac{5 \times 3}{2 \times 2} = \frac{15}{4} = 3 \frac{3}{4}
   $$
1. $$2 \frac{1}{4} \div \frac{3}{4} = 3$$ 2. $$3 \frac{2}{5} \div \frac{1}{5} = 17$$ 3. $$7 \frac{2}{4} \div \frac{5}{10} = 15$$ 4. $$2 \frac{3}{6} \div \frac{2}{3} = 3 \frac{3}{4}$$
