1.Kotae

[tex]1 \frac{2}{3} \times 2\frac{1}{4} = \\ \frac{5}{3} \times \frac{9}{4} = \\ \frac{5 \times 9}{3 \times 4} = \\ \frac{45}{12} = 3 \frac{9}{12} \\ 3\frac{9}{12} \div 3 = 3 \frac{1}{4} [/tex]

2.Kotae

[tex]0.5 \times 50\% = \\ \frac{5}{10} \times \frac{50}{100} = \\ \frac{5 \times 50}{10 \times 100} = \\ \frac{250}{1.000} = \frac{25}{100} = \frac{1}{4} [/tex]

3.Kotae

[tex] \frac{3}{4} \times 0.5 = \\ \frac{3}{4} \times \frac{5}{10} = \\ \frac{3 \times 5}{4 \times 10} = \\ \frac{15}{40} = \frac{3}{8} [/tex]

[tex] \frac{3}{4} \div \frac{1}{4} = \\ \frac{3}{4} \times \frac{4}{1} = \\ \frac{3 \times 4}{4 \times 1} = \\ \frac{12}{4} = 3[/tex]

5.☺Kotae

[tex]3 \frac{1}{2} \div 1 \frac{1}{4} = \\ \frac{7}{2} \div \frac{5}{4} = \\ \frac{7}{2 } \times \frac{4}{5} = \\ \frac{7 \times 4}{2 \times 5} = \\ \frac{28}{10} = \frac{14}{5} = 2 \frac{4}{5} [/tex]
