$$\frac{2}{5}+\frac{1}{5}=?$$

$$\frac{2}{5}+\frac{1}{5}=\frac{2+1}{5}=\frac{3}{5}$$

$$\frac{2}{5}+\frac{1}{5}=\frac{2+1}{5+5}=\frac{3}{10}$$

$$\frac{2}{5}+\frac{1}{5}=\frac{1}{5+5}=\frac{1}{10}$$

$$\frac{2}{3}+\frac{4}{5}=?$$

$$\frac{2}{3}+\frac{4}{5}=\frac{10}{15}+\frac{12}{15}=\frac{22}{15}$$

$$\frac{2}{3}+\frac{4}{5}=\frac{2}{3}+\frac{4}{3}=\frac{6}{3}=2$$

$$\frac{2}{3}+\frac{4}{5}=\frac{2+4}{3+5}=\frac{6}{8}=\frac{3}{4}$$

$$\frac{1}{2}+\frac{1}{3}=?$$

$$\frac{1}{2}+\frac{1}{3}=\frac{3}{6}+\frac{2}{6}=\frac{5}{6}$$

$$\frac{1}{2}+\frac{1}{3}=\frac{1+1}{2+3}=\frac{2}{5}$$

$$\frac{1}{2}+\frac{1}{3}=\frac{1}{2+3}=\frac{1}{5}$$
