Find the Mean 12 , 18 , 24

$12$ , $18$ , $24$

Step 1

The mean of a set of numbers is the sum divided by the number of terms.

$\frac{12 + 18 + 24}{3}$

Step 2

Cancel the common factor of $12 + 18 + 24$ and $3$ .

Factor $3$ out of $12$ .

$\frac{3 \cdot 4 + 18 + 24}{3}$

Factor $3$ out of $18$ .

$\frac{3 \cdot 4 + 3 \cdot 6 + 24}{3}$

Factor $3$ out of $3 \cdot 4 + 3 \cdot 6$ .

$\frac{3 \cdot (4 + 6) + 24}{3}$

Factor $3$ out of $24$ .

$\frac{3 \cdot (4 + 6) + 3 \cdot 8}{3}$

Factor $3$ out of $3 \cdot (4 + 6) + 3 (8)$ .

$\frac{3 \cdot (4 + 6 + 8)}{3}$

Cancel the common factors.

Factor $3$ out of $3$ .

$\frac{3 \cdot (4 + 6 + 8)}{3 (1)}$

Cancel the common factor.

$\frac{3 \cdot (4 + 6 + 8)}{3 \cdot 1}$

Rewrite the expression.

$\frac{4 + 6 + 8}{1}$

Divide $4 + 6 + 8$ by $1$ .

$4 + 6 + 8$

Step 3

Simplify by adding numbers.

Add $4$ and $6$ .

$10 + 8$

Add $10$ and $8$ .

$18$
