Solve 3-1/2-6

$$3- \frac{ 1 }{ 2 } -6$$

Evaluate

$$-\frac{7}{2}=-3.5$$

Solution Steps

Convert 3 to fraction \frac{6}{2}.

$$\frac{6}{2}-\frac{1}{2}-6$$

Since \frac{6}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{6-1}{2}-6$$

Subtract 1 from 6 to get 5.

$$\frac{5}{2}-6$$

Convert 6 to fraction \frac{12}{2}.

$$\frac{5}{2}-\frac{12}{2}$$

Since \frac{5}{2} and \frac{12}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{5-12}{2}$$

Subtract 12 from 5 to get -7.

$$-\frac{7}{2}$$

Factor

$$-\frac{7}{2} = -3\frac{1}{2} = -3.5$$
