Runners

Thirty chocolates are prepared and distributed in the ratio of 3:2:1 for three runners (in first to third place).

How much chocolate will get everyone?

Final Answer:

a =  15
b =  10
c =  5

Step-by-step explanation:

$$\begin{gathered} D=\frac{30}{3+2+1}=5 \\ a=3\cdot D=3\cdot 5=15 \end{gathered}$$

$b=2\cdot D=2\cdot 5=10$

$c=1\cdot D=1\cdot 5=5$
