Chapter 1: Q26. (page 20)

Evaluate the following expression and name the property used in each step:
$3 .5 \cdot 3 \cdot 6$

Short Answer

Expert verified

The value of the expression is: $3 .5 \cdot 3 \cdot 6 = 63$ .

Step by step solution

Step 1. Given information.

The given expression is:

$3.5 \cdot 3 \cdot 6$

Step 2. Write the concept.

The substitution property for multiplication, addition, and subtraction is:

$\begin{array}{l} a \cdot b = c \\ a \div b = c \\ a \pm b = c \end{array}$

The Commutative property of multiplication is:

$a \cdot b = b \cdot a$

Step 3. Evaluate the expression.

The expression $3.5 \cdot 3 \cdot 6$ can be solved below:

$\begin{array}{l} 3.5 \cdot 3 \cdot 6 = (3.5 \cdot 6) \cdot 3 [Commutative Property] \\ = (21) \cdot 3 [Substitution Property] \\ = 63 [Substitution Property] \end{array}$
