Daca paharele sunt de 0,25l atunci:
1 pahar..........0,25l
x pahare..…...7l
[tex] \frac{1}{x} = \frac{0.25}{7} [/tex]
[tex]0.25 = \frac{1}{4} [/tex]
[tex] \frac{0.25}{7} = \frac{1}{4} \div \frac{7}{1} = \frac{1}{4} \times \frac{1}{7} = \frac{1}{28} [/tex]
[tex] \frac{1}{x} = \frac{1}{28} [/tex]
[tex]x = \frac{1 \times 28}{1} = 28[/tex]
Ai nevoie de 28 de pahare
