Solve -32/7+13/7

$$- 3 \frac { 2 } { 7 } + 1 \frac { 3 } { 7 }$$

Evaluate

$$-\frac{13}{7}\approx -1.857142857$$

Solution Steps

Multiply 3 and 7 to get 21.

$$-\frac{21+2}{7}+\frac{1\times 7+3}{7}$$

Add 21 and 2 to get 23.

$$-\frac{23}{7}+\frac{1\times 7+3}{7}$$

Multiply 1 and 7 to get 7.

$$-\frac{23}{7}+\frac{7+3}{7}$$

Add 7 and 3 to get 10.

$$-\frac{23}{7}+\frac{10}{7}$$

Since -\frac{23}{7} and \frac{10}{7} have the same denominator, add them by adding their numerators.

$$\frac{-23+10}{7}$$

Add -23 and 10 to get -13.

$$-\frac{13}{7}$$

Factor

$$-\frac{13}{7} = -1\frac{6}{7} = -1.8571428571428572$$
