[tex] \frac{2}{5} + \frac{2}{3} \times \frac{2}{4} = \\ \frac{2}{5} + \frac{2}{3} \times \frac{2}{4} \\ \frac{2}{5} + \frac{2}{3} \times \frac{2}{4}aqui \\ risque \: o \: numero \: 2 \: e \: 4 \\ \frac{2}{5} + \frac{2}{3} \times \frac{1}{2} \\ \frac{2}{5} + \frac{2}{3} \times \frac{1}{2}aqui \\ risque \: os \: numeros \: 2 \: e \: 2 \\ \frac{2}{5} + \frac{1}{3} \\ \frac{6 + 5}{15} \\ \frac{11}{15} \\ \frac{2}{5} + \frac{1}{3} \\ \frac{11}{15} \\ resposta \\ \frac{11}{15} [/tex]
