Solution Steps

Add 6.4 and 2.9 to get 9.3.

$$9.3+5.6+4.7+7+4.7+2.3+3.8+4.1+6.9+5.2$$

Add 9.3 and 5.6 to get 14.9.

$$14.9+4.7+7+4.7+2.3+3.8+4.1+6.9+5.2$$

Add 14.9 and 4.7 to get 19.6.

$$19.6+7+4.7+2.3+3.8+4.1+6.9+5.2$$

Add 19.6 and 7 to get 26.6.

$$26.6+4.7+2.3+3.8+4.1+6.9+5.2$$

Add 26.6 and 4.7 to get 31.3.

$$31.3+2.3+3.8+4.1+6.9+5.2$$

Add 31.3 and 2.3 to get 33.6.

$$33.6+3.8+4.1+6.9+5.2$$

Add 33.6 and 3.8 to get 37.4.

$$37.4+4.1+6.9+5.2$$

Add 37.4 and 4.1 to get 41.5.

$$41.5+6.9+5.2$$

Add 41.5 and 6.9 to get 48.4.

$$48.4+5.2$$

Add 48.4 and 5.2 to get 53.6.

$$53.6$$

Factor

$$\frac{67 \cdot 2 ^ {2}}{5} = 53\frac{3}{5} = 53.6$$
