Wanted book

Kianna had 48 Eur, and Kyle had 42 Eur. Kyle shared 1/6 of his money, and Kianna shared 1/8 of her money to buy a book that they both wanted to read. How much money did they share to buy the book?

Correct answer:

x =  13 Eur

Step-by-step explanation:

$$\begin{gathered} a=48\cdot \frac{1}{8}=\frac{48\cdot 1}{8}=\frac{48}{8}=6\text{Eur} \\ b=42\cdot \frac{1}{6}=\frac{42\cdot 1}{6}=\frac{42}{6}=7\text{Eur} \\ x=a+b=6+7=13\text{Eur} \end{gathered}$$
