Question

Evaluate the expression 4mn/-2p when m = 1/2, n = -3, and p = 3

Answer 1

To evaluate the expression \( \frac{4mn}{-2p} \) when \( m = \frac{1}{2} \), \( n = -3 \), and \( p = 3 \), we start by substituting the values of \( m \), \( n \), and \( p \) into the expression.

1. Substitute the values:
\[
m = \frac{1}{2}, \quad n = -3, \quad p = 3
\]

2. Substitute into the expression:
\[
\frac{4 \cdot \frac{1}{2} \cdot (-3)}{-2 \cdot 3}
\]

3. Calculate the numerator:
\[
4 \cdot \frac{1}{2} = 2
\]
Then:
\[
2 \cdot (-3) = -6
\]
Therefore, the numerator is \( -6 \).

4. Calculate the denominator:
\[
-2 \cdot 3 = -6
\]

5. The expression now looks like this:
\[
\frac{-6}{-6}
\]

6. Simplify the fraction:
\[
\frac{-6}{-6} = 1
\]

Thus, the value of the expression \( \frac{4mn}{-2p} \) is \( \boxed{1} \).
