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

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

Evaluate

$$-\frac{13}{12}\approx -1.083333333$$

Solution Steps

Least common multiple of 3 and 4 is 12. Convert -\frac{1}{3} and \frac{3}{4} to fractions with denominator 12.

$$-\frac{4}{12}-\frac{9}{12}$$

Since -\frac{4}{12} and \frac{9}{12} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-4-9}{12}$$

Subtract 9 from -4 to get -13.

$$-\frac{13}{12}$$

Factor

$$-\frac{13}{12} = -1\frac{1}{12} = -1.0833333333333333$$
