Solve -15/8+7/8-2/8

$$-1 \frac{ 5 }{ 8 } + \frac{ 7 }{ 8 } - \frac{ 2 }{ 8 }$$

Evaluate

$$-1$$

Solution Steps

Multiply 1 and 8 to get 8.

$$-\frac{8+5}{8}+\frac{7}{8}-\frac{2}{8}$$

Add 8 and 5 to get 13.

$$-\frac{13}{8}+\frac{7}{8}-\frac{2}{8}$$

Since -\frac{13}{8} and \frac{7}{8} have the same denominator, add them by adding their numerators.

$$\frac{-13+7}{8}-\frac{2}{8}$$

Add -13 and 7 to get -6.

$$\frac{-6}{8}-\frac{2}{8}$$

Reduce the fraction \frac{-6}{8} to lowest terms by extracting and canceling out 2.

$$-\frac{3}{4}-\frac{2}{8}$$

Reduce the fraction \frac{2}{8} to lowest terms by extracting and canceling out 2.

$$-\frac{3}{4}-\frac{1}{4}$$

Since -\frac{3}{4} and \frac{1}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-3-1}{4}$$

Subtract 1 from -3 to get -4.

$$\frac{-4}{4}$$

Divide -4 by 4 to get -1.

$$-1$$

Factor

$$-1$$
