Solve (-2/3)+(-3/9)+(+5/8)

$$( - \frac { 2 } { 3 } ) + ( - \frac { 3 } { 9 } ) + ( + \frac { 5 } { 8 } )$$

Evaluate

$$-\frac{3}{8}=-0.375$$

Solution Steps

Reduce the fraction \frac{3}{9} to lowest terms by extracting and canceling out 3.

$$-\frac{2}{3}-\frac{1}{3}+\frac{5}{8}$$

Since -\frac{2}{3} and \frac{1}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-2-1}{3}+\frac{5}{8}$$

Subtract 1 from -2 to get -3.

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

Divide -3 by 3 to get -1.

$$-1+\frac{5}{8}$$

Convert -1 to fraction -\frac{8}{8}.

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

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

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

Add -8 and 5 to get -3.

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

Factor

$$-\frac{3}{8} = -0.375$$
