Problem Analysis

We are given that Kira, Lena, and Zhenya each wrote down one expression in their notebooks. Among the three expressions, one is an equality and two are inequalities. Additionally, the expressions written by Kira and Zhenya are the same. We need to determine the name of the expression written by Lena.

Solution

To solve this problem, let's analyze the given information step by step:

1. Kira, Lena, and Zhenya each wrote down one expression in their notebooks. 2. Among the three expressions, one is an equality and two are inequalities. 3. The expressions written by Kira and Zhenya are the same.

Based on this information, we can conclude that Lena must have written down the equality expression. This is because if Kira and Zhenya wrote down the same expression, it cannot be the equality expression since there can only be one equality expression among the three.

Therefore, the expression written by Lena is an equality expression.

Conclusion

The expression written by Lena is an equality expression.
