$$2 \cdot 42.55+ \frac{ 1 }{ 2 } 205 \cdot 138-121.2$$

Evaluate

$$14108.9$$

Solution Steps

Multiply 2 and 42.55 to get 85.1.

$$85.1+\frac{1}{2}\times 205\times 138-121.2$$

Multiply \frac{1}{2} and 205 to get \frac{205}{2}.

$$85.1+\frac{205}{2}\times 138-121.2$$

Express \frac{205}{2}\times 138 as a single fraction.

$$85.1+\frac{205\times 138}{2}-121.2$$

Multiply 205 and 138 to get 28290.

$$85.1+\frac{28290}{2}-121.2$$

Divide 28290 by 2 to get 14145.

$$85.1+14145-121.2$$

Add 85.1 and 14145 to get 14230.1.

$$14230.1-121.2$$

Subtract 121.2 from 14230.1 to get 14108.9.

$$14108.9$$

Factor

$$\frac{13 \cdot 10853}{2 \cdot 5} = 14108\frac{9}{10} = 14108.9$$
