Solve -5/4+3/2-3/2

$$- \frac { 5 } { 4 } + \frac { 3 } { 2 } - \frac { 3 } { 2 }$$

Evaluate

$$-\frac{5}{4}=-1.25$$

Solution Steps

Least common multiple of 4 and 2 is 4. Convert -\frac{5}{4} and \frac{3}{2} to fractions with denominator 4.

$$-\frac{5}{4}+\frac{6}{4}-\frac{3}{2}$$

Since -\frac{5}{4} and \frac{6}{4} have the same denominator, add them by adding their numerators.

$$\frac{-5+6}{4}-\frac{3}{2}$$

Add -5 and 6 to get 1.

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

Least common multiple of 4 and 2 is 4. Convert \frac{1}{4} and \frac{3}{2} to fractions with denominator 4.

$$\frac{1}{4}-\frac{6}{4}$$

Since \frac{1}{4} and \frac{6}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{1-6}{4}$$

Subtract 6 from 1 to get -5.

$$-\frac{5}{4}$$

Factor

$$-\frac{5}{4} = -1\frac{1}{4} = -1.25$$
