[tex](3 \frac{5}{7} - 2 \frac{11}{27} ) \div (3 \frac{4}{7} - 2 \frac{1}{2}) = ( \frac{26}{7} - \frac{65}{27} ) \div ( \frac{25}{7} - \frac{5}{2} ) = \frac{247}{189} \div \frac{15}{14} = \frac{247}{189} \times \frac{14}{15} = \frac{247}{27} \times \frac{2}{15} = \frac{494}{405} = 1 \frac{89}{405} \\ [/tex]
Mam nadzieję że pomogłam ❤️
