Simplify the fractions:

We are asked to simplify the fractions $$\frac{18}{48}$$ and $$\frac{7}{28}$$. First, consider the fraction $$\frac{18}{48}$$. The greatest common divisor (GCD) of 18 and 48 is 6. So, we can divide both the numerator and denominator by 6: $$\frac{18}{48} = \frac{18 \div 6}{48 \div 6} = \frac{3}{8}$$ Next, consider the fraction $$\frac{7}{28}$$. The greatest common divisor (GCD) of 7 and 28 is 7. So, we can divide both the numerator and denominator by 7: $$\frac{7}{28} = \frac{7 \div 7}{28 \div 7} = \frac{1}{4}$$ So, the simplified fractions are $$\frac{3}{8}$$ and $$\frac{1}{4}$$. **Answers:** $$\frac{18}{48} = \frac{3}{8}$$ $$\frac{7}{28} = \frac{1}{4}$$
