Solve 1-5/4-3/2=

$$1 - \frac { 5 } { 4 } - \frac { 3 } { 2 } =$$

Evaluate

$$-\frac{7}{4}=-1.75$$

Solution Steps

Convert 1 to fraction \frac{4}{4}.

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

Since \frac{4}{4} and \frac{5}{4} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 5 from 4 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 -7.

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

Factor

$$-\frac{7}{4} = -1\frac{3}{4} = -1.75$$
