$$- \frac { 1 } { 4 } + \frac { 1 } { 2 } + 12$$

Evaluate

$$\frac{49}{4}=12.25$$

Solution Steps

Least common multiple of 4 and 2 is 4. Convert -\frac{1}{4} and \frac{1}{2} to fractions with denominator 4.

$$-\frac{1}{4}+\frac{2}{4}+12$$

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

$$\frac{-1+2}{4}+12$$

Add -1 and 2 to get 1.

$$\frac{1}{4}+12$$

Convert 12 to fraction \frac{48}{4}.

$$\frac{1}{4}+\frac{48}{4}$$

Since \frac{1}{4} and \frac{48}{4} have the same denominator, add them by adding their numerators.

$$\frac{1+48}{4}$$

Add 1 and 48 to get 49.

$$\frac{49}{4}$$

Factor

$$\frac{7 ^ {2}}{2 ^ {2}} = 12\frac{1}{4} = 12.25$$
