Answer: 1/9 > 1/11 (c)
Explanation:
To compare these fractions, we must first make sure that they have common (the same) denominators. The easiest way to do this is to multiply 9*11, to ensure that both fractions have a denominator of 99. To do this, we must multiply both the numerator and denominator of 1/9 by 11, and the numerator and denominator of 1/11 by 9.
1/9 * 11/11 = 11/99
1/11 * 9/9 = 9/99
Now we have equivalent fractions that can be compared. Because 11/99 is greater than 9/99, the correct answer is c.
