![]()
[tex]2 \frac{2}{3} \div 1 \frac{2}{3} - 4 \frac{1}{5} [/tex]
[tex] = \frac{(2 \times 3 + 2) \times 3}{3(1 \times 3 + 2)} - \frac{4 \times 5 + 1}{5} [/tex]
[tex] = \frac{2 + 2 \times 3}{2 + 3} - \frac{4 \times 5 + 1}{5} [/tex]
[tex] = \frac{2 + 6}{2 + 3} - \frac{4 \times 5 + 1}{5} [/tex]
[tex] = \frac{8}{2 + 3} - \frac{4 \times 5 + 1}{5} [/tex]
[tex] = \frac{8}{5} - \frac{4 \times 5 + 1}{5} [/tex]
[tex] = \frac{8}{5} - \frac{20 + 1}{5} [/tex]
[tex] = \frac{8}{5} - \frac{21}{5} [/tex]
[tex] = \frac{8 - 21}{5} [/tex]
[tex] = - \frac{13}{5} [/tex]
