1. Problem Description

The problem asks us to compare 3233\frac{2}{3} and 11\sqrt{11}. We need to determine if 3233\frac{2}{3} is less than, greater than, or equal to 11\sqrt{11}.

2. Solution Steps

First, convert the mixed number 3233\frac{2}{3} to an improper fraction:
323=3×3+23=9+23=1133\frac{2}{3} = \frac{3 \times 3 + 2}{3} = \frac{9 + 2}{3} = \frac{11}{3}.
Now, we want to compare 113\frac{11}{3} with 11\sqrt{11}. To make the comparison easier, we can square both numbers:
(113)2=11232=1219(\frac{11}{3})^2 = \frac{11^2}{3^2} = \frac{121}{9}
(11)2=11(\sqrt{11})^2 = 11
Next, we can express 11 as a fraction with a denominator of 9:
11=11×99=99911 = \frac{11 \times 9}{9} = \frac{99}{9}
Now we can compare 1219\frac{121}{9} and 999\frac{99}{9}. Since 121>99121 > 99, we have 1219>999\frac{121}{9} > \frac{99}{9}.
Therefore, (113)2>(11)2(\frac{11}{3})^2 > (\sqrt{11})^2.
Since both 113\frac{11}{3} and 11\sqrt{11} are positive numbers, if their squares satisfy an inequality, then the numbers themselves also satisfy the same inequality.
Thus, 113>11\frac{11}{3} > \sqrt{11}, which means 323>113\frac{2}{3} > \sqrt{11}.

3. Final Answer

323>113\frac{2}{3} > \sqrt{11}
