Combine $200$ and $\frac{7}{3}$ .

$4, \frac{200 \cdot 7}{3}$

Multiply $200$ by $7$ .

$4, \frac{1400}{3}$

Step 3

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

$\frac{4 + \frac{1400}{3}}{2}$

Step 4

Cancel the common factor of $4 + \frac{1400}{3}$ and $2$ .

Factor $2$ out of $4$ .

$\frac{2 \cdot 2 + \frac{1400}{3}}{2}$

Factor $2$ out of $\frac{1400}{3}$ .

$\frac{2 \cdot 2 + 2 (\frac{700}{3})}{2}$

Factor $2$ out of $2 \cdot 2 + 2 (\frac{700}{3})$ .

$\frac{2 \cdot (2 + \frac{700}{3})}{2}$

Cancel the common factors.

Factor $2$ out of $2$ .

$\frac{2 \cdot (2 + \frac{700}{3})}{2 (1)}$

Cancel the common factor.

$\frac{2 \cdot (2 + \frac{700}{3})}{2 \cdot 1}$

Rewrite the expression.

$\frac{2 + \frac{700}{3}}{1}$

Divide $2 + \frac{700}{3}$ by $1$ .

$2 + \frac{700}{3}$

Step 5

To write $2$ as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$2 \cdot \frac{3}{3} + \frac{700}{3}$

Step 6

Combine $2$ and $\frac{3}{3}$ .

$\frac{2 \cdot 3}{3} + \frac{700}{3}$

Step 7
