To solve the problem using an area model with shaded and unshaded parts, we have the shaded parts representing \( \frac{4}{5} \) and we need to divide this by \( \frac{1}{10} \).
The question we want to ask is: "How many times does \( \frac{1}{10} \) fit into \( \frac{4}{5} \)?"
To find the answer, we can rewrite the division of fractions as multiplication by the reciprocal:
\[ \frac{4}{5} \div \frac{1}{10} = \frac{4}{5} \times \frac{10}{1} \]
Now, we can multiply:
\[ = \frac{4 \times 10}{5 \times 1} = \frac{40}{5} = 8 \]
So, the quotient is \( 8 \).
