Step-by-Step Solution

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:

  • First, determine the reciprocal of 110\frac{1}{10}. The reciprocal of a fraction is obtained by swapping its numerator and denominator. Thus, the reciprocal of 110\frac{1}{10} is 101\frac{10}{1}.
  • Now multiply 15\frac{1}{5} by the reciprocal of 110\frac{1}{10}, which is 101\frac{10}{1}:

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

Therefore, the result of 15:110\frac{1}{5} : \frac{1}{10} is 22.
