Solve -(+13/4)+(+5/6)=

$$- ( + 1 \frac { 3 } { 4 } ) + ( + \frac { 5 } { 6 } ) =$$

Evaluate

$$-\frac{11}{12}\approx -0.916666667$$

Solution Steps

Multiply 1 and 4 to get 4.

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

Add 4 and 3 to get 7.

$$-\frac{7}{4}+\frac{5}{6}$$

Least common multiple of 4 and 6 is 12. Convert -\frac{7}{4} and \frac{5}{6} to fractions with denominator 12.

$$-\frac{21}{12}+\frac{10}{12}$$

Since -\frac{21}{12} and \frac{10}{12} have the same denominator, add them by adding their numerators.

$$\frac{-21+10}{12}$$

Add -21 and 10 to get -11.

$$-\frac{11}{12}$$

Factor

$$-\frac{11}{12} = -0.9166666666666666$$
