Solve 31/3-42/3=

$$3 \frac { 1 } { 3 } - 4 \frac { 2 } { 3 } =$$

Evaluate

$$-\frac{4}{3}\approx -1.333333333$$

Solution Steps

Multiply 3 and 3 to get 9.

$$\frac{9+1}{3}-\frac{4\times 3+2}{3}$$

Add 9 and 1 to get 10.

$$\frac{10}{3}-\frac{4\times 3+2}{3}$$

Multiply 4 and 3 to get 12.

$$\frac{10}{3}-\frac{12+2}{3}$$

Add 12 and 2 to get 14.

$$\frac{10}{3}-\frac{14}{3}$$

Since \frac{10}{3} and \frac{14}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{10-14}{3}$$

Subtract 14 from 10 to get -4.

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

Factor

$$-\frac{4}{3} = -1\frac{1}{3} = -1.3333333333333333$$
