Answer explanation

To divide a mixed number by a fraction, convert the mixed number to an improper fraction, then multiply by the reciprocal of the divisor. In this case, 1\frac{1}{10} = \frac{11}{10}, so \frac{11}{10} \div \frac{4}{5} = \frac{11}{10} \times \frac{5}{4} = \frac{55}{40} = 1\frac{9}{10}. Therefore, the correct answer is 1\frac{9}{10}.
