The expression $2\frac{1}{2}·\left(-\frac{1}{4}\right)$.

Mixed fractions of the form $m\frac{p}{q}$can be converted into proper fractions as,

$m\frac{p}{q}=\frac{\left(m×q\right)+p}{q}$

The product of two real numbers is obtained when they are multiplied together. That is two or more numbers are separated by multiplication signs $\left(\right),×\mathrm{or}·$.

The product of a negative and a positive integer is always negative.

Consider the expression $2\frac{1}{2}·\left(-\frac{1}{4}\right)$.

Recall that mixed fractions of the form $m\frac{p}{q}$can be converted into proper fractions as

$m\frac{p}{q}=\frac{\left(m×q\right)+p}{q}$

So, $2\frac{1}{2}$will be converted as,

$$\begin{gathered} 2\frac{1}{2}=\frac{\left(2×2\right)+1}{2} \\ =\frac{5}{2} \end{gathered}$$

Recall that product of two real numbers is obtained when they are multiplied together. That is two or more numbers are separated by multiplication signs $\left(\right),×\mathrm{or}·$.

Simplify it,

$\begin{array}{c}\frac{5}{2}·\left(-\frac{1}{4}\right)=-\frac{1·5}{2·4}\\ =-\frac{5}{8}\end{array}$

Thus, the simplified value of the expression $2\frac{1}{2}·\left(-\frac{1}{4}\right)$is $-\frac{5}{8}$.
