[tex]1.75 + \frac{1}{2} = 1.75 + 0.50 = 2.25 = 2 \frac{1}{4} [/tex]
[tex] \frac{1}{4} \times 0.3 = \frac{1}{4} \times \frac{3}{10} = \frac{3}{40} [/tex]
[tex]2.2 - \frac{1}{5} = 2.2 - 0.2 = 2[/tex]
[tex] \frac{3}{25} \div 0.75 = \frac{3}{25} \div \frac{75}{100} = \frac{4}{25} [/tex]
[tex]1.75 + \frac{1}{2} = 1 \frac{3}{4} + \frac{1}{2} = 2 \frac{1}{4} [/tex]
[tex] \frac{1}{4} \times 0.3 = 0.25 \times 0.3 = 0.075[/tex]
[tex]2.2 - \frac{1}{5} = 2 \frac{1}{5} - \frac{1}{5} = 2[/tex]
[tex] \frac{3}{25} \div 0.75 = 0.12 \div 0.75 = 0.16[/tex]
Mam nadzieję że pomogłem
