Find each product or quotient where possible. See Example 2. (12⁄13)/( -4⁄3)

Verified step by step guidance
1
Identify the operation between the two fractions. Here, the expression is \( \frac{12}{13} \times \left(-\frac{4}{3}\right) \), which is a multiplication of two fractions.
Recall the rule for multiplying fractions: multiply the numerators together and multiply the denominators together. So, the product is \( \frac{12 \times (-4)}{13 \times 3} \).
Calculate the numerator by multiplying 12 and -4, and calculate the denominator by multiplying 13 and 3, but do not simplify yet.
Write the resulting fraction from step 3 as \( \frac{12 \times (-4)}{13 \times 3} \) and then simplify the fraction by finding any common factors between numerator and denominator.
Express the simplified fraction as the final product of the original multiplication problem.
