Question

The simplified value of the expression $0.75\left(-6.4\right)$.

Step-by-Step Solution

Answer

The simplified value of the expression $0.75\left(-6.4\right)$ is $-4.8$.

Step 1.

The expression $0.75\left(-6.4\right)$.

Step 2. Concept.

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

 

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

Step 3. Calculation.

Consider the expression $0.75\left(-6.4\right)$.

 

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 $\left(\right),\times \mathrm{or}·$.

 

Simplify it,

$\begin{array}{c}0.75\left(-6.4\right)=-\left(0.75·6.4\right)\\ =-4.8\end{array}$

Thus, the simplified value of the expression $0.75\left(-6.4\right)$ is $-4.8$.
