[tex]7 \times 2 \frac{1}{5} = 7 \times \frac{11}{5} = \frac{77}{5} = 15 \frac{2}{5} [/tex]
[tex]1 \frac{5}{7} \times 3 = \frac{12}{7} \times 3 = \frac{36}{7} = 5 \frac{1}{7} [/tex]
[tex]5 \frac{1}{3} \times 10 = \frac{16}{3} \times 10 = \frac{160}{3} = 53 \frac{1}{3} [/tex]
Odpowiedź:
7*11/5 = 77/5 = 15 2/5
12/7*3 = 36:7 = 5 1/7
16/3*10 = 160:3 = 53 1/3
