Solve 1/2-13/4=

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

Evaluate

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

Solution Steps

Multiply 1 and 4 to get 4.

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

Add 4 and 3 to get 7.

$$\frac{1}{2}-\frac{7}{4}$$

Least common multiple of 2 and 4 is 4. Convert \frac{1}{2} and \frac{7}{4} to fractions with denominator 4.

$$\frac{2}{4}-\frac{7}{4}$$

Since \frac{2}{4} and \frac{7}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{2-7}{4}$$

Subtract 7 from 2 to get -5.

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

Factor

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