Solution Steps

Add 10.9 and 12.5 to get 23.4.

$$23.4+16+19.4+9.8+6.7+14.1+14.9+9.5+15+17.7$$

Add 23.4 and 16 to get 39.4.

$$39.4+19.4+9.8+6.7+14.1+14.9+9.5+15+17.7$$

Add 39.4 and 19.4 to get 58.8.

$$58.8+9.8+6.7+14.1+14.9+9.5+15+17.7$$

Add 58.8 and 9.8 to get 68.6.

$$68.6+6.7+14.1+14.9+9.5+15+17.7$$

Add 68.6 and 6.7 to get 75.3.

$$75.3+14.1+14.9+9.5+15+17.7$$

Add 75.3 and 14.1 to get 89.4.

$$89.4+14.9+9.5+15+17.7$$

Add 89.4 and 14.9 to get 104.3.

$$104.3+9.5+15+17.7$$

Add 104.3 and 9.5 to get 113.8.

$$113.8+15+17.7$$

Add 113.8 and 15 to get 128.8.

$$128.8+17.7$$

Add 128.8 and 17.7 to get 146.5.

$$146.5$$

Factor
