Solve (-1/8-5/4+3/8)

$$( - \frac { 1 } { 8 } - \frac { 5 } { 4 } + \frac { 3 } { 8 } )$$

Evaluate

$$-1$$

Solution Steps

Least common multiple of 8 and 4 is 8. Convert -\frac{1}{8} and \frac{5}{4} to fractions with denominator 8.

$$-\frac{1}{8}-\frac{10}{8}+\frac{3}{8}$$

Since -\frac{1}{8} and \frac{10}{8} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-1-10}{8}+\frac{3}{8}$$

Subtract 10 from -1 to get -11.

$$-\frac{11}{8}+\frac{3}{8}$$

Since -\frac{11}{8} and \frac{3}{8} have the same denominator, add them by adding their numerators.

$$\frac{-11+3}{8}$$

Add -11 and 3 to get -8.

$$\frac{-8}{8}$$

Divide -8 by 8 to get -1.

$$-1$$
