Odpowiedź:
Zad 7
b)
[tex] \frac{200}{150} = \frac{200 \div 50}{150 \div 50} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
c)
[tex] \frac{60}{36} = \frac{60 \div 12}{36 \div 12} = \frac{5}{3} = 1 \frac{2}{3} [/tex]
d)
[tex] \frac{660}{240} = \frac{660 \div 60}{240 \div 60} = \frac{11}{4} = 2 \frac{3}{4} [/tex]
Zad 8
a) dobrze
b)
[tex] \frac{7}{2} = 3 \frac{1}{2} [/tex]
c) dobrze
d)
[tex] \frac{64}{12} = \frac{64 \div 4}{12 \div 4} = \frac{16}{3} = 5 \frac{1}{3} [/tex]
e)
[tex] \frac{25}{3} = 8 \frac{1}{3} [/tex]
f)
[tex] \frac{39}{5} = 7 \frac{4}{5} [/tex]
Zad 9
[tex] \frac{4}{4} = 1[/tex]
[tex] \frac{7}{4} = 1 \frac{3}{4} [/tex]
[tex] \frac{8}{4} = 2[/tex]
[tex] \frac{9}{4} = 2 \frac{1}{4} [/tex]
