Answer

$\frac{5}{9}\gt\frac{6}{11}$

Work Step by Step

The least common multiplier of the denominators is 99, since $ 9\times 11= 99$ Adjust the fractions based on the least common multiplier. For the first fraction, multiply the numerator and denominator by 11. $ \frac{5}{9}\times \frac{11}{11}= \frac{55}{99}$ For the second multiplier, multiply the numerator and denominator by 9. $ \frac{6}{11} \times \frac{9}{9}= \frac{54}{99}$ $\frac{55}{99}\gt \frac{54}{99}$ So, $\frac{5}{9}\gt\frac{6}{11}$
