24pqr:(-4pq)

To simplify the expression \( \frac{24pqr}{-4pq} \), you can start by simplifying the coefficients and the variables.

1. Simplify the coefficients: \[ \frac{24}{-4} = -6 \]

2. Simplify the variables: \[ \frac{pqr}{pq} = \frac{r}{1} = r \]

Putting it all together, you get: \[ \frac{24pqr}{-4pq} = -6r \]

So, the simplified expression is \(-6r\).
