3/8 :(-5/8)

To divide \( \frac{3}{8} \) by \( -\frac{5}{8} \), you can multiply by the reciprocal of the divisor. So, the expression becomes: \[ \frac{3}{8} \div -\frac{5}{8} = \frac{3}{8} \times -\frac{8}{5} \] Now, multiply the fractions: \[ \frac{3 \times -8}{8 \times 5} = \frac{-24}{40} \] Now, simplify \( \frac{-24}{40} \): The greatest common divisor (GCD) of 24 and 40 is 8. So, \[ \frac{-24 \div 8}{40 \div 8} = \frac{-3}{5} \] Thus, \[ \frac{3}{8} \div -\frac{5}{8} = -\frac{3}{5} \]
