To divide the fractions \(-\frac{5}{8}\) by \(-\frac{2}{3}\), you can multiply the first fraction by the reciprocal of the second fraction.
- Flip the second fraction: \(-\frac{2}{3}\) becomes \(-\frac{3}{2}\).
- Multiply \(-\frac{5}{8}\) by \(-\frac{3}{2}\):
\[ -\frac{5}{8} \div -\frac{2}{3} = -\frac{5}{8} \times -\frac{3}{2} \]
- Multiply the numerators and the denominators:
\[ = \frac{5 \times 3}{8 \times 2} = \frac{15}{16} \]
Thus, the quotient of \(-\frac{5}{8} \div -\frac{2}{3}\) is \(\frac{15}{16}\).
