Chapter 1, Problem 59

Find each product or quotient where possible. -3/8 (-24/9)

Verified step by step guidance
1
Identify the problem as a multiplication of two fractions: \(-\frac{3}{8} \times -\frac{24}{9}\).
Multiply the numerators together: \(-3 \times -24\) and multiply the denominators together: \(8 \times 9\) to get a new fraction.
Simplify the numerator and denominator separately before multiplying if possible, by factoring and reducing common factors.
After simplification, multiply the simplified numerators and denominators to get the product fraction.
If possible, reduce the resulting fraction to its simplest form by dividing numerator and denominator by their greatest common divisor (GCD).
