Small and large bread

Kipton's aunt bakes a large loaf of bread and a small loaf of bread. She cuts each loaf into tenths and gives Kipton 2 tenths of each loaf to take home. Kipton writes the equation 2/10 + 2/10 = 4/10 to show the amount of bread he takes home. Explain Kipton's mistake.

Correct answer:

x =  0

Step-by-step explanation:

$$\begin{gathered} a\ne b \\ \frac{2}{10}\cdot a+\frac{2}{10}\cdot b\ne \frac{4}{10} \\ x=0 \end{gathered}$$
