What is $$\frac{2}{4} - \frac{3}{8}$$ ?

Convert $$\frac{2}{4}$$ to $$\frac{4}{8}$$ . Then, subtract: $$\frac{4}{8} - \frac{3}{8} = \frac{1}{8}$$ .

What is the difference between $$\frac{8}{9}$$ and $$\frac{1}{3}$$ ?

Convert $$\frac{1}{3}$$ to $$\frac{3}{9}$$ . Then, subtract: $$\frac{8}{9} - \frac{3}{9} = \frac{5}{9}$$ .
