Question

7 litri in cate pahare incap

Answer 1

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