[tex] - \frac{1}{3} \times 5 \frac{3}{5} = - \frac{1}{3} \times \frac{5 \times 5 + 3}{5} = - \frac{1}{3} \times \frac{25 + 3}{5} = - \frac{1}{3} \times \frac{28}{5} = - \frac{28}{15} = - 1 \frac{13}{15 } \\ [/tex]
[tex]-\frac{1}{3} \cdot5\frac{3}{5}= -\frac{1}{3} \cdot\frac{5\cdot5+3}{5}=-\frac{1}{3} \cdot\frac{28}{5}=-\frac{1\cdot28}{3\cdot5}=-\frac{28}{15}=-1\frac{13}{15}[/tex]
