Solve 21/3-17/3

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

Evaluate

$$-1$$

Solution Steps

Multiply 2 and 3 to get 6.

$$\frac{6+1}{3}-\frac{1\times 3+7}{3}$$

Add 6 and 1 to get 7.

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

Multiply 1 and 3 to get 3.

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

Add 3 and 7 to get 10.

$$\frac{7}{3}-\frac{10}{3}$$

Since \frac{7}{3} and \frac{10}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{7-10}{3}$$

Subtract 10 from 7 to get -3.

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

Divide -3 by 3 to get -1.

$$-1$$

Factor

$$-1$$
