$2 \frac{1}{6}$

We first subtract the whole numbers: $4-1=3$ In order to add or subtract fractions, we need common denominators. Because 1/12 and 11/12 already have the same denominator, 12, we can subtract the numerators: $ \frac{1}{12} - \frac{11}{12} =- \frac{10}{12}=-\frac{5}{6}$ We add 3 to get an answer of $2 \frac{1}{6}$
