a)
[tex] \frac{4}{5} \div \frac{2}{7} = \frac{4}{5} \times \frac{7}{2} = \frac{2}{5} \times \frac{7}{1} = \frac{14}{5} = 2 \frac{4}{5} [/tex]
b)
[tex]6 \div \frac{5}{2} = 6 \times \frac{2}{5} = \frac{12}{5} = 2 \frac{2}{5} [/tex]
c)
[tex]1 \frac{2}{3} \div \frac{4}{5} = \frac{5}{3} \times \frac{5}{4} = \frac{25}{12} = 2 \frac{1}{12} [/tex]
Myślę że pomogłem ;)
Odpowiedź:
4/5 : 2/7 = 4/5 * 7/2 = 14/5 = 2 i 4/5
6 : 5/2 = 6 * 2/5 = 12/5 = 2 i 2/5
1 i 2/3 : 4/5 = 5/3 : 4/5 = 5/3 * 5/4 = 25/12 = 2 i 1/12
