Odpowiedź:
A)
[tex]4 \times 5 \frac{1}{3} = 4 \times \frac{16}{3} = \frac{64}{3} = 21 \frac{1}{3} [/tex]
B)
[tex]9 \times \frac{1}{5} = \frac{9}{5} = 1 \frac{4}{5} [/tex]
C)
[tex]2 \frac{3}{7} \times 4 = \frac{17}{7} \times 4 = \frac{68}{7} = 9 \frac{8}{7} [/tex]
D)
[tex]3 \frac{2}{9} \times 5 = \frac{29}{9} \times 5 = \frac{145}{9} = 16 \frac{1}{9} [/tex]
E)
[tex]4 \frac{1}{4} \times 7 = \frac{17}{4} \times 7 = \frac{119}{4} = 29 \frac{3}{4} [/tex]
F)
[tex]6 \times 2 \frac{5}{12} = 6 \times \frac{29}{12} = 1 \times \frac{29}{6} = 4 \frac{5}{6} [/tex]
