Solve -7/8+-12/3

$$- \frac { 7 } { 8 } + - 1 \frac { 2 } { 3 }$$

Evaluate

$$-\frac{61}{24}\approx -2.541666667$$

Solution Steps

Multiply 1 and 3 to get 3.

$$-\frac{7}{8}-\frac{3+2}{3}$$

Add 3 and 2 to get 5.

$$-\frac{7}{8}-\frac{5}{3}$$

Least common multiple of 8 and 3 is 24. Convert -\frac{7}{8} and \frac{5}{3} to fractions with denominator 24.

$$-\frac{21}{24}-\frac{40}{24}$$

Since -\frac{21}{24} and \frac{40}{24} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-21-40}{24}$$

Subtract 40 from -21 to get -61.

$$-\frac{61}{24}$$

Factor

$$-\frac{61}{24} = -2\frac{13}{24} = -2.5416666666666665$$
