MR-517 / 2. problem

If 1 kg of salami is 2800 HUF, how much will cost 35 dkg salami?

$↓ \begin{matrix} 350 g & x F t \\ 1000 g & 2800 F t \end{matrix} ↓$

$350 g : 1000 g = x F t : 2800 F t$

$350 : 1000 = x : 2800$

$350 \cdot 2800 = 1000 \cdot x$

$x = \frac{350 \cdot 2800}{1000}$

$x = 980 F t$
