Add $34$ and $75$ .

$\frac{109 + 26 + 81 + 65 + 38 + 49 + 894}{8}$

Add $109$ and $26$ .

$\frac{135 + 81 + 65 + 38 + 49 + 894}{8}$

Add $135$ and $81$ .

$\frac{216 + 65 + 38 + 49 + 894}{8}$

Add $216$ and $65$ .

$\frac{281 + 38 + 49 + 894}{8}$

Add $281$ and $38$ .

$\frac{319 + 49 + 894}{8}$

Add $319$ and $49$ .

$\frac{368 + 894}{8}$

Add $368$ and $894$ .

$\frac{1262}{8}$

Step 3

Cancel the common factor of $1262$ and $8$ .

Factor $2$ out of $1262$ .

$\frac{2 (631)}{8}$

Cancel the common factors.

Factor $2$ out of $8$ .

$\frac{2 \cdot 631}{2 \cdot 4}$

Cancel the common factor.

$\frac{2 \cdot 631}{2 \cdot 4}$
