Solve -51/3+42/3

$$- 5 \frac { 1 } { 3 } + 4 \frac { 2 } { 3 }$$

Evaluate

$$-\frac{2}{3}\approx -0.666666667$$

Solution Steps

Multiply 5 and 3 to get 15.

$$-\frac{15+1}{3}+\frac{4\times 3+2}{3}$$

Add 15 and 1 to get 16.

$$-\frac{16}{3}+\frac{4\times 3+2}{3}$$

Multiply 4 and 3 to get 12.

$$-\frac{16}{3}+\frac{12+2}{3}$$

Add 12 and 2 to get 14.

$$-\frac{16}{3}+\frac{14}{3}$$

Since -\frac{16}{3} and \frac{14}{3} have the same denominator, add them by adding their numerators.

$$\frac{-16+14}{3}$$

Add -16 and 14 to get -2.

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

Factor

$$-\frac{2}{3} = -0.6666666666666666$$
