Step 1. Given information

The fraction $\frac{13}{15}, \frac{11}{18}$ .

Step 2. Calculation

To evaluate the greater fraction in $\frac{13}{15}, \frac{11}{18}$ , it is needed to calculate the least common multiple of 15,18.

Therefore, the least common multiple of 15, 18 is 90 and this will be least common denominator of fraction $\frac{13}{15}, \frac{11}{18}$ .

Make equivalent fraction of each fraction by least common denominator.

$\begin{array}{l} \frac{13}{15} = \frac{13 \times 6}{15 \times 6}; \frac{11}{18} = \frac{11 \times 5}{18 \times 5} \\ \frac{13}{15} = \frac{78}{90} ; \frac{11}{18} = \frac{55}{90} \end{array}$

As the equivalent fractional of $\frac{13}{15}, \frac{11}{18}$ have same denominator so compare the numerator

$78 > 55$

$\frac{13}{15} > \frac{11}{18}$

Hence, the fraction $\frac{13}{15}$ is greater than fraction $\frac{11}{18}$
