  1. 7 9/26

  2. 0.724

  3. 2 5/8

The correct answer is: 3/77

To convert the mixed number 9 11/21 into an improper fraction, you can follow these steps: First, multiply the whole number (9) by the denominator of the fraction (21). This gives you 9 * 21 = 189. Next, add the numerator (11) to this product: 189 + 11 = 200. Now, place this sum over the original denominator: 200/21. This represents the mixed number 9 11/21 as an improper fraction. The correct answer is not reflected in your choice, but the improper fraction would be 200/21. The other provided choices do not represent the correct conversion of the mixed number into a fraction. Understanding how to convert mixed numbers into improper fractions is crucial for solving various mathematical problems efficiently.
