Solve -9/4+1/4-1/2

$$- \frac{ 9 }{ 4 } + \frac{ 1 }{ 4 } - \frac{ 1 }{ 2 }$$

Evaluate

$$-\frac{5}{2}=-2.5$$

Solution Steps

Since -\frac{9}{4} and \frac{1}{4} have the same denominator, add them by adding their numerators.

$$\frac{-9+1}{4}-\frac{1}{2}$$

Add -9 and 1 to get -8.

$$\frac{-8}{4}-\frac{1}{2}$$

Divide -8 by 4 to get -2.

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

Convert -2 to fraction -\frac{4}{2}.

$$-\frac{4}{2}-\frac{1}{2}$$

Since -\frac{4}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-4-1}{2}$$

Subtract 1 from -4 to get -5.

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

Factor

$$-\frac{5}{2} = -2\frac{1}{2} = -2.5$$
