Evaluate the expression `\frac{3mn}{-2p}` when `m\ =\ \frac{1}{3},` `n\ =-3,`and `p=3.` try

1 answer

To evaluate the expression \(\frac{3mn}{-2p}\) with the given values \(m = \frac{1}{3}\), \(n = -3\), and \(p = 3\), we can follow these steps:

  1. Substitute the values of \(m\), \(n\), and \(p\) into the expression: \[ \frac{3 \left(\frac{1}{3}\right)(-3)}{-2(3)} \]

  2. Simplify the numerator: \[ 3 \left(\frac{1}{3}\right)(-3) = 3 \cdot \frac{1}{3} \cdot -3 = 1 \cdot -3 = -3 \]

  3. Simplify the denominator: \[ -2(3) = -6 \]

  4. Now we have the fraction: \[ \frac{-3}{-6} \]

  5. Simplifying \(\frac{-3}{-6}\): \[ \frac{-3}{-6} = \frac{3}{6} = \frac{1}{2} \]

Thus, the value of the expression \(\frac{3mn}{-2p}\) is \(\frac{1}{2}\).
