Problem
1) \( \frac{2}{9}, \frac{10}{15 n} \) A) \( \frac{4 n^{2}}{3} \) B) 5 C) \( \frac{4}{270} \) D) \( \frac{17 t}{5} \)
Solution
Step 1 ：Find the least common denominator (LCD): \( \text{LCD}(9,15n)=45n \)
Step 2 ：Rewrite the fractions with the LCD: \( \frac{2}{9} = \frac{10n}{45n} \), \( \frac{10}{15n} = \frac{3}{45n} \)
Step 3 ：Compare the rewritten fractions: \( \frac{10n}{45n} > \frac{3}{45n} \)
