Let's solve the problem step by step, interpreting the markings and the information provided.
We are working with Roman numerals for the numbers 11 through 20. Here is a detailed breakdown of each number along with their corresponding Roman numerals:
- 11 is "XI"
- 12 is "XII"
- 13 is "XIII"
- 14 is "XIV"
- 15 is "XV"
- 16 is "XVI"
- 17 is "XVII"
- 18 is "XVIII"
- 19 is "XIX"
- 20 is "XX"
The problem specifies markings for 11 and 20 specifically. Let's analyze these:
- For 11: The numeral is "XI" and there is an indication (×) next to it.
- For 20: The numeral is "XX" and there is a mark (××) next to it.
Given the interpretations:
- The number 11 has a multiplication sign (×) next to it, indicating it should be singled out or highlighted for some reason.
- Similarly, the number 20 has two multiplication signs (××) next to it.
Based on this:
For the numbers 11 and 20:
- 11 in Roman numeral is "XI", and it's marked as important (×).
- 20 in Roman numeral is "XX", and it's also marked as important (××).
The resulting output would be:
[tex]\[
\begin{aligned}
&11 \rightarrow \text{XI} \, ( \text{Important}) \\
&20 \rightarrow \text{XX} \, ( \text{Important}) \\
\end{aligned}
\][/tex]
Summarizing, the numbers 11 and 20 are specifically highlighted due to their respective importance marks. Their Roman numerals are "XI" for 11 and "XX" for 20.
