$$\frac{2}{3}\left(39.2+4\times 6.8+2\times 5.6+4\times 5+2\times 4.8+4\times 4.8+0\right)$$

Multiply 4 and 6.8 to get 27.2.

$$\frac{2}{3}\left(39.2+27.2+2\times 5.6+4\times 5+2\times 4.8+4\times 4.8+0\right)$$

Add 39.2 and 27.2 to get 66.4.

$$\frac{2}{3}\left(66.4+2\times 5.6+4\times 5+2\times 4.8+4\times 4.8+0\right)$$

Multiply 2 and 5.6 to get 11.2.

$$\frac{2}{3}\left(66.4+11.2+4\times 5+2\times 4.8+4\times 4.8+0\right)$$

Add 66.4 and 11.2 to get 77.6.

$$\frac{2}{3}\left(77.6+4\times 5+2\times 4.8+4\times 4.8+0\right)$$

Multiply 4 and 5 to get 20.

$$\frac{2}{3}\left(77.6+20+2\times 4.8+4\times 4.8+0\right)$$

Add 77.6 and 20 to get 97.6.

$$\frac{2}{3}\left(97.6+2\times 4.8+4\times 4.8+0\right)$$

Multiply 2 and 4.8 to get 9.6.

$$\frac{2}{3}\left(97.6+9.6+4\times 4.8+0\right)$$

Add 97.6 and 9.6 to get 107.2.

$$\frac{2}{3}\left(107.2+4\times 4.8+0\right)$$

Multiply 4 and 4.8 to get 19.2.

$$\frac{2}{3}\left(107.2+19.2+0\right)$$

Add 107.2 and 19.2 to get 126.4.

$$\frac{2}{3}\left(126.4+0\right)$$

Add 126.4 and 0 to get 126.4.
