Solve 12/3-31/3

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

Evaluate

$$-\frac{5}{3}\approx -1.666666667$$

Solution Steps

Multiply 1 and 3 to get 3.

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

Add 3 and 2 to get 5.

$$\frac{5}{3}-\frac{3\times 3+1}{3}$$

Multiply 3 and 3 to get 9.

$$\frac{5}{3}-\frac{9+1}{3}$$

Add 9 and 1 to get 10.

$$\frac{5}{3}-\frac{10}{3}$$

Since \frac{5}{3} and \frac{10}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{5-10}{3}$$

Subtract 10 from 5 to get -5.

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

Factor

$$-\frac{5}{3} = -1\frac{2}{3} = -1.6666666666666667$$
