Solve 12.8*4+11.4+15.7*3+12.8+7+4.2*3

$$12.8 \times 4+11.4+15.7 \times 3+12.8+7+4.2 \times 3$$

Evaluate

$$142.1$$

Solution Steps

Multiply 12.8 and 4 to get 51.2.

$$51.2+11.4+15.7\times 3+12.8+7+4.2\times 3$$

Add 51.2 and 11.4 to get 62.6.

$$62.6+15.7\times 3+12.8+7+4.2\times 3$$

Multiply 15.7 and 3 to get 47.1.

$$62.6+47.1+12.8+7+4.2\times 3$$

Add 62.6 and 47.1 to get 109.7.

$$109.7+12.8+7+4.2\times 3$$

Add 109.7 and 12.8 to get 122.5.

$$122.5+7+4.2\times 3$$

Add 122.5 and 7 to get 129.5.

$$129.5+4.2\times 3$$

Multiply 4.2 and 3 to get 12.6.

$$129.5+12.6$$

Add 129.5 and 12.6 to get 142.1.

$$142.1$$

Factor

$$\frac{29 \cdot 7 ^ {2}}{2 \cdot 5} = 142\frac{1}{10} = 142.1$$
