Solve -3/2--5/8=

$$\frac{ -3 }{ 2 } - \frac{ -5 }{ 8 } =$$

Evaluate

$$-\frac{7}{8}=-0.875$$

Solution Steps

Fraction \frac{-3}{2} can be rewritten as -\frac{3}{2} by extracting the negative sign.

$$-\frac{3}{2}-\frac{-5}{8}$$

Fraction \frac{-5}{8} can be rewritten as -\frac{5}{8} by extracting the negative sign.

$$-\frac{3}{2}-\left(-\frac{5}{8}\right)$$

The opposite of -\frac{5}{8} is \frac{5}{8}.

$$-\frac{3}{2}+\frac{5}{8}$$

Least common multiple of 2 and 8 is 8. Convert -\frac{3}{2} and \frac{5}{8} to fractions with denominator 8.

$$-\frac{12}{8}+\frac{5}{8}$$

Since -\frac{12}{8} and \frac{5}{8} have the same denominator, add them by adding their numerators.

$$\frac{-12+5}{8}$$

Add -12 and 5 to get -7.

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