Solve 6*4left(3+9right)3-1/2

$$6 \cdot 4 \left( 3+9 \right) 3- \frac{ 1 }{ 2 }$$

Evaluate

$$\frac{1727}{2}=863.5$$

Solution Steps

Multiply 6 and 4 to get 24.

$$24\left(3+9\right)\times 3-\frac{1}{2}$$

Add 3 and 9 to get 12.

$$24\times 12\times 3-\frac{1}{2}$$

Multiply 24 and 12 to get 288.

$$288\times 3-\frac{1}{2}$$

Multiply 288 and 3 to get 864.

$$864-\frac{1}{2}$$

Convert 864 to fraction \frac{1728}{2}.

$$\frac{1728}{2}-\frac{1}{2}$$

Since \frac{1728}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{1728-1}{2}$$

Subtract 1 from 1728 to get 1727.

$$\frac{1727}{2}$$

Factor

$$\frac{11 \cdot 157}{2} = 863\frac{1}{2} = 863.5$$
