Solve 30*12+20*1.6*1.2+18.1*15.8*1.4

$$30 \times 12 + 20 \times 1.6 \times 1.2 + 18.1 \times 15.8 \times 1.4$$

Evaluate

$$798.772$$

Solution Steps

Multiply 30 and 12 to get 360.

$$360+20\times 1.6\times 1.2+18.1\times 15.8\times 1.4$$

Multiply 20 and 1.6 to get 32.

$$360+32\times 1.2+18.1\times 15.8\times 1.4$$

Multiply 32 and 1.2 to get 38.4.

$$360+38.4+18.1\times 15.8\times 1.4$$

Add 360 and 38.4 to get 398.4.

$$398.4+18.1\times 15.8\times 1.4$$

Multiply 18.1 and 15.8 to get 285.98.

$$398.4+285.98\times 1.4$$

Multiply 285.98 and 1.4 to get 400.372.

$$398.4+400.372$$

Add 398.4 and 400.372 to get 798.772.

$$798.772$$

Factor

$$\frac{13 \cdot 15361}{2 \cdot 5 ^ {3}} = 798\frac{193}{250} = 798.772$$
