Explanation opens after your attempt
Correct Answer
A. \( \frac{11}{15} \)
Step 1
Concept
The middle value is \( \frac{\frac{2}{3}+\frac{4}{5}}{2}=\frac{11}{15} \). You can take the average to find a number between two numbers.
Step 2
Why this answer is correct
The correct answer is A. \( \frac{11}{15} \). The middle value is \( \frac{\frac{2}{3}+\frac{4}{5}}{2}=\frac{11}{15} \). You can take the average to find a number between two numbers.
Step 3
Exam Tip
मध्य मान \( \frac{\frac{2}{3}+\frac{4}{5}}{2}=\frac{11}{15} \) है। दो संख्याओं के बीच संख्या के लिए औसत ले सकते हैं।
