Dividends

The three friends divided the win by the invested money. Karlos got three-eighths, John 320 permille, and the rest got Martin. Who got the most and which the least?

Correct answer:

k =  0.375
j =  0.32
m =  0.305

Step-by-step explanation:

$k=3\mathrm{/}8={\displaystyle \frac{3}{8}}=0.375$

$j=320\mathrm{/}1000={\displaystyle \frac{8}{25}}=0.32$

$$\begin{gathered} m=1-k-j=1-0.375-0.32={\displaystyle \frac{61}{200}}=0.305 \\ m<j<k \\ m=0.305={\displaystyle \frac{61}{200}}=0.305 \end{gathered}$$
