$$\frac{2910+540+360+360}{1+1+3+3+3+4}$$

Add 2910 and 540 to get 3450.

$$\frac{3450+360+360}{1+1+3+3+3+4}$$

Add 3450 and 360 to get 3810.

$$\frac{3810+360}{1+1+3+3+3+4}$$

Add 3810 and 360 to get 4170.

$$\frac{4170}{1+1+3+3+3+4}$$

Add 1 and 1 to get 2.

$$\frac{4170}{2+3+3+3+4}$$

Add 2 and 3 to get 5.

$$\frac{4170}{5+3+3+4}$$

Add 5 and 3 to get 8.

$$\frac{4170}{8+3+4}$$
