$\frac{12}{5} = 2 \frac{2}{5}$

$\frac{9}{4} = 2 \frac{1}{4}$

$2 \frac{2}{3} = \frac{8}{3}$

$2 \frac{4}{9} = \frac{22}{9}$

$\frac{3}{5} + 1 \frac{4}{5} = 1 \frac{7}{5} = 2 \frac{2}{5}$

$1 \frac{1}{4} + 2 \frac{3}{5} = 1 \frac{5}{20} + 2 \frac{12}{20} = 3 \frac{17}{20}$

$1 \frac{3}{11} - \frac{6}{11} = \frac{14}{11} - \frac{6}{11} = \frac{8}{11}$

$5 \frac{5}{6} - 2 \frac{2}{3} = 5 \frac{5}{6} - 2 \frac{4}{6} = 3 \frac{1}{6}$

$15 \times 4 \frac{2}{3} = \frac{15}{1} \times \frac{14}{3} = 5 \times 14 = 70$

$1 \frac{1}{3} \times 3 \frac{3}{4} = \frac{4}{3} \times \frac{15}{4} = \frac{1}{1} \times \frac{5}{1} = 5$

$3 \frac{3}{4} \div 12 = \frac{15}{4} \times \frac{1}{12} = \frac{5}{4} \times \frac{1}{4} = \frac{5}{16}$

$7 \frac{1}{3} \div 1\frac{4}{7} = \frac{22}{3} \div \frac{11}{7} = \frac{22}{3} \times \frac{7}{11} = \frac{2}{3} \times \frac{7}{1} = \frac{14}{3} = 4 \frac{2}{3}$

$\frac{3}{10} i \frac{3}{11} \\ \\ \frac{33}{110} > \frac{30}{110}$

Odpowiedź:

12/5 = 2 2/5

9/4 = 2 1/4

2 2/3 = 14/3

2 4/9 = 22/9

3/5 + 1 4/5 = 1 7/5 = 2 2/5

1 1/4 + 2 3/5 = 1 5/20 + 2 12/20 = 3 17/20

1 3/11 - 6/11 = 14/11 - 6/11 = 8/11

15 * 4 2/3 = 15 * 14/3 = 5 * 14 = 70

1 1/3 * 3 3/4 = 4/3 * 15/4 = 5

3 3/4 : 12 = 15/4 * 1/12 = 5/4 * 1/4 = 5/16

7 1/3 : 1 4/7 = 22/3 : 11/7 = 22/3 * 7/11 = 14/3 = 4 2/3

Janek - 3/10 = 33/110

Ania - 3/11 = 30/110

33/110 > 30/110
