Solve -7/12-3/2-5

$$- \frac{ 7 }{ 12 } - \frac{ 3 }{ 2 } -5$$

Evaluate

$$-\frac{85}{12}\approx -7.083333333$$

Solution Steps

Least common multiple of 12 and 2 is 12. Convert -\frac{7}{12} and \frac{3}{2} to fractions with denominator 12.

$$-\frac{7}{12}-\frac{18}{12}-5$$

Since -\frac{7}{12} and \frac{18}{12} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-7-18}{12}-5$$

Subtract 18 from -7 to get -25.

$$-\frac{25}{12}-5$$

Convert 5 to fraction \frac{60}{12}.

$$-\frac{25}{12}-\frac{60}{12}$$

Since -\frac{25}{12} and \frac{60}{12} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-25-60}{12}$$

Subtract 60 from -25 to get -85.

$$-\frac{85}{12}$$

Factor

$$-\frac{85}{12} = -7\frac{1}{12} = -7.083333333333333$$
