1.
a)
kolorujemy 3 koraliki
kolorujemy 6 koralików
kolorujemy 9 koralików
b)
[tex] \frac{1}{5} \times 15 = \frac{1}{1} \times 3 = 3[/tex]
[tex] \frac{2}{5} \times 15 = \frac{2}{1} \times 3 = 6[/tex]
[tex] \frac{3}{5} \times 15 = \frac{3}{1} \times 3 = 9[/tex]
2.
a)
[tex] \frac{1}{3} \times 18 = \frac{1}{1} \times 6 = 6[/tex]
[tex] \frac{2}{9} \times 18 = \frac{2}{1} \times 2 = 4[/tex]
[tex] \frac{4}{9} \times 18 = \frac{4}{1} \times 2 = 8[/tex]
3.
a)
[tex] \frac{1}{5} \times 40 = \frac{1}{1} \times 8 = 8[/tex]
b)
[tex] \frac{1}{3} \times 21 = \frac{1}{1} \times 7 = 7[/tex]
c)
[tex] \frac{1}{4} \times 100 = \frac{1}{1} \times 25 = 25[/tex]
d)
[tex] \frac{3}{4} \times 60 = \frac{3}{1} \times 15 = 45[/tex]
e)
[tex]1 \frac{3}{4} \times 1000 = \frac{7}{4} \times 1000 = \frac{7}{1} \times 250 = 1750[/tex]
Myślę że pomogłem ;)
