To solve this problem, we need to divide the fraction 15\frac{1}{5} by the fraction 110\frac{1}{10}. When dividing fractions, the procedure involves multiplying by the reciprocal of the divisor (the second fraction).

Let's start with the solution:

15×101=1×105×1=105\frac{1}{5} \times \frac{10}{1} = \frac{1 \times 10}{5 \times 1} = \frac{10}{5}

Simplify the fraction 105\frac{10}{5}:

105=2\frac{10}{5} = 2
