[tex]2 \frac{1}{3} \times 3 - 4 \div 5 \frac{1}{3} = \frac{7}{3} \times 3 - 4 \div \frac{16}{3} = 7 - 4 \times \frac{3}{16} = 7 - \frac{3}{4} = 6 \frac{1}{4} [/tex]
[tex]1 \frac{1}{2} (2 - \frac{3}{4} \div 6) = \frac{3}{2} (2 - \frac{3}{4} \times \frac{1}{6} ) = \frac{3}{2} ( \frac{2}{1} - \frac{1}{8} ) = \frac{3}{2} ( \frac{16}{8} - \frac{1}{8} ) = \frac{3}{2} \times \frac{15}{8} = \frac{45}{16} = 2 \frac{13}{16} [/tex]
Myślę że pomogłem ;)
