Guida verificata passo dopo passo
1
Identify the problem as a multiplication of two fractions: \(-\frac{5}{2} \times \frac{12}{15}\).
Multiply the numerators together: \(-5 \times 12\) and multiply the denominators together: \(2 \times 15\) to get a new fraction.
Write the product as \(\frac{-5 \times 12}{2 \times 15}\), which simplifies to \(\frac{-60}{30}\) before reducing.
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor (GCD).
Express the simplified fraction as the final product of the multiplication.
