Solve -1/2+23/4=

$$- \frac { 1 } { 2 } + 2 \frac { 3 } { 4 } =$$

Evaluate

$$\frac{9}{4}=2.25$$

Solution Steps

Multiply 2 and 4 to get 8.

$$-\frac{1}{2}+\frac{8+3}{4}$$

Add 8 and 3 to get 11.

$$-\frac{1}{2}+\frac{11}{4}$$

Least common multiple of 2 and 4 is 4. Convert -\frac{1}{2} and \frac{11}{4} to fractions with denominator 4.

$$-\frac{2}{4}+\frac{11}{4}$$

Since -\frac{2}{4} and \frac{11}{4} have the same denominator, add them by adding their numerators.

$$\frac{-2+11}{4}$$

Add -2 and 11 to get 9.

$$\frac{9}{4}$$

Factor

$$\frac{3 ^ {2}}{2 ^ {2}} = 2\frac{1}{4} = 2.25$$
