Jeníček, Karel, and Martin shared the money from the brigade in a ratio of 2:4:3. Karel received the most, namely 12.60 euros. How much did Jeníček and Martin get together?

Correct answer:

J =  6.3 Eur
M =  9.45 Eur

Step-by-step explanation:

$$\begin{gathered} K=12.60 \\ x=K/4=12.6/4=\frac{63}{20}=3.15 \\ J=2\cdot x=2\cdot 3.15=6.3\text{Eur} \end{gathered}$$

$M=3\cdot x=3\cdot 3.15=9.45\text{Eur}$
