Add $152$ and $73$ .

$\frac{225 + 47 + 22 + 46 + 34 + 48 + 67 + 89 + 83 + 12 + 23 + 44 + 16}{15}$

Add $225$ and $47$ .

$\frac{272 + 22 + 46 + 34 + 48 + 67 + 89 + 83 + 12 + 23 + 44 + 16}{15}$

Add $272$ and $22$ .

$\frac{294 + 46 + 34 + 48 + 67 + 89 + 83 + 12 + 23 + 44 + 16}{15}$

Add $294$ and $46$ .

$\frac{340 + 34 + 48 + 67 + 89 + 83 + 12 + 23 + 44 + 16}{15}$

Add $340$ and $34$ .

$\frac{374 + 48 + 67 + 89 + 83 + 12 + 23 + 44 + 16}{15}$

Add $374$ and $48$ .

$\frac{422 + 67 + 89 + 83 + 12 + 23 + 44 + 16}{15}$

Add $422$ and $67$ .

$\frac{489 + 89 + 83 + 12 + 23 + 44 + 16}{15}$

Add $489$ and $89$ .

$\frac{578 + 83 + 12 + 23 + 44 + 16}{15}$

Add $578$ and $83$ .

$\frac{661 + 12 + 23 + 44 + 16}{15}$

Add $661$ and $12$ .

$\frac{673 + 23 + 44 + 16}{15}$

Add $673$ and $23$ .

$\frac{696 + 44 + 16}{15}$

Add $696$ and $44$ .

$\frac{740 + 16}{15}$

Add $740$ and $16$ .

$\frac{756}{15}$

Step 3

Cancel the common factor of $756$ and $15$ .

Factor $3$ out of $756$ .

$\frac{3 (252)}{15}$

Cancel the common factors.

Factor $3$ out of $15$ .

$\frac{3 \cdot 252}{3 \cdot 5}$

Cancel the common factor.

$\frac{3 \cdot 252}{3 \cdot 5}$

Rewrite the expression.

$\frac{252}{5}$

Step 4

Divide.
