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

$\frac{1.7 + 3.2 + 2.8 + 2.3}{4}$

Step 2

Simplify the numerator.

Add $1.7$ and $3.2$ .

$\frac{4.9 + 2.8 + 2.3}{4}$

Add $4.9$ and $2.8$ .

$\frac{7.7 + 2.3}{4}$

Add $7.7$ and $2.3$ .

$\frac{10}{4}$

Step 3

Cancel the common factor of $10$ and $4$ .

Factor $2$ out of $10$ .

$\frac{2 (5)}{4}$

Cancel the common factors.

Factor $2$ out of $4$ .

$\frac{2 \cdot 5}{2 \cdot 2}$

Cancel the common factor.

$\frac{2 \cdot 5}{2 \cdot 2}$

Rewrite the expression.

$\frac{5}{2}$

Step 4

Divide.

$2.5$
