Solve -3/-8--3/4=

$$\frac { - 3 } { - 8 } - \frac { - 3 } { 4 } =$$

Evaluate

$$\frac{9}{8}=1.125$$

Solution Steps

Fraction \frac{-3}{-8} can be simplified to \frac{3}{8} by removing the negative sign from both the numerator and the denominator.

$$\frac{3}{8}-\frac{-3}{4}$$

Fraction \frac{-3}{4} can be rewritten as -\frac{3}{4} by extracting the negative sign.

$$\frac{3}{8}-\left(-\frac{3}{4}\right)$$

The opposite of -\frac{3}{4} is \frac{3}{4}.

$$\frac{3}{8}+\frac{3}{4}$$

Least common multiple of 8 and 4 is 8. Convert \frac{3}{8} and \frac{3}{4} to fractions with denominator 8.

$$\frac{3}{8}+\frac{6}{8}$$

Since \frac{3}{8} and \frac{6}{8} have the same denominator, add them by adding their numerators.

$$\frac{3+6}{8}$$

Add 3 and 6 to get 9.

$$\frac{9}{8}$$

Factor

$$\frac{3 ^ {2}}{2 ^ {3}} = 1\frac{1}{8} = 1.125$$
