Problem 14. What is the missing bottom left number if the top number is 2 rac16 and the bottom right number is 3 rac16? The pattern is (Bottom Left) - (Bottom Right) = Top.

The top number is $2\frac{1}{6}$.
The bottom right number is $3\frac{1}{6}$.
Let the missing bottom left number be $X$.

Add the whole numbers: $2 + 3 = 5$.
Add the fractions: $\frac{1}{6} + \frac{1}{6} = \frac{2}{6}$.

Simplify the fraction $\frac{2}{6}$ by dividing the numerator and denominator by 2: $\frac{2 \div 2}{6 \div 2} = \frac{1}{3}$.

The missing value for is \boxed{\text{5\frac{1}{3}}}.
