There is exchange trade on the market. We know that for two sheepskins we get three goat skins. We also know that for six rabbits skins we get four goat skins. How many rabbit's skins we get for four sheepskins?

Correct answer:

x =  9

Step-by-step explanation:

$$\begin{gathered} 2o=3k \\ 6z=4k \\ 4o=3\cdot 2k \\ 4o=6k \\ 6\cdot {\displaystyle \frac{6}{4}}z=4\cdot {\displaystyle \frac{6}{4}}k \\ x=6\cdot {\displaystyle \frac{6}{4}}=9 \end{gathered}$$
