Find each product or quotient where possible. See Example 2. (-4⁄5) / (-3⁄5)

Guida verificata passo dopo passo

Identify the operation between the two fractions. Here, the problem shows two fractions written side by side: \(-\frac{4}{5}\) and \(-\frac{3}{5}\). This typically means multiplication of the two fractions.

Recall the rule for multiplying fractions: multiply the numerators together and multiply the denominators together. So, the product of \(-\frac{4}{5}\) and \(-\frac{3}{5}\) is given by \(\left(-\frac{4}{5}\right) \times \left(-\frac{3}{5}\right) = \frac{(-4) \times (-3)}{5 \times 5}\).

Calculate the numerator by multiplying the two numerators: \((-4) \times (-3)\). Remember that multiplying two negative numbers results in a positive number.

Calculate the denominator by multiplying the two denominators: \(5 \times 5\).

Write the product as a single fraction with the numerator and denominator found in the previous steps. Then, if possible, simplify the fraction by dividing numerator and denominator by their greatest common divisor.
