[tex]a) \: \: \frac{1}{4} \times 1.6 = \frac{1}{4} \times \frac{16}{10} = \frac{4}{10} = \frac{2}{5} [/tex]
[tex]3.6 \times \frac{1}{3} = \frac{36}{10} \times \frac{1}{3} = \frac{12}{10} = \frac{6}{5} = 1 \frac{1}{5} [/tex]
[tex]b) \: \: \frac{4}{7} \div 3.2 = \frac{4}{7} \div \frac{32}{10} = \frac{4}{7} \times \frac{10}{32} = \frac{10}{56} = \frac{5}{28} [/tex]
[tex]1.8 \div \frac{2}{5} = \frac{18}{10} \times \frac{5}{2} = \frac{9}{2} = 4 \frac{1}{2} [/tex]
Mam nadzieję, że pomogłam! ❤️
