$\frac{135 + 25 + 19 + 35}{8}$

Add $135$ and $25$ .

$\frac{160 + 19 + 35}{8}$

Add $160$ and $19$ .

$\frac{179 + 35}{8}$

Add $179$ and $35$ .

$\frac{214}{8}$

Step 3

Cancel the common factor of $214$ and $8$ .

Factor $2$ out of $214$ .

$\frac{2 (107)}{8}$

Cancel the common factors.

Factor $2$ out of $8$ .

$\frac{2 \cdot 107}{2 \cdot 4}$
