$\frac{3}{4} + \frac{5}{3} = \frac{9}{12} + \frac{20}{12} = \frac{29}{12} = 2 \frac{5}{12}$

$\frac{3}{4} - \frac{5}{3} = \frac{9}{12} - \frac{20}{12} = - \frac{11}{12}$

$\frac{3}{4} \times \frac{5}{3} = \frac{1}{4} \times \frac{5}{1} = \frac{5}{4} = 1\frac{1}{4}$

$\frac{3}{4} \div \frac{5}{3} = \frac{3}{4} \times \frac{3}{5} = \frac{9}{20}$

$2 \frac{1}{5} \times 2 \frac{1}{4} = \frac{11}{5} \times \frac{9}{4} = \frac{99}{20} = 4 \frac{19}{20}$

$5 \frac{1}{2} \div 3\frac{1}{4} = \frac{11}{2} \div \frac{13}{4} = \frac{11}{2} \times \frac{4}{13} = \frac{11}{1} \times \frac{2}{13} = \frac{22}{13} = 1 \frac{9}{13}$

Myślę że pomogłem ;)

Odpowiedź:

3/4 + 5/3 = 9/12 + 20/12 = 29/12 = 2 i 5/12

3/4 - 5/3 = 9/12 - 20/12 = -11/12

3/4 * 5/3 = 5/4 = 1 i 1/4

3/4 : 5/3 = 3/4 * 3/5 = 9/20

2 i 1/5 * 2 i 1/4 = 11/5 * 9/4 = 99/20 = 4 i 19/20

5 i 1/2 : 3 i 1/4 = 11/2 * 4/13 = 22/13 = 1 i 9/13
