Solve 42/3-21/3=

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

Evaluate

$$\frac{7}{3}\approx 2.333333333$$

Solution Steps

Multiply 4 and 3 to get 12.

$$\frac{12+2}{3}-\frac{2\times 3+1}{3}$$

Add 12 and 2 to get 14.

$$\frac{14}{3}-\frac{2\times 3+1}{3}$$

Multiply 2 and 3 to get 6.

$$\frac{14}{3}-\frac{6+1}{3}$$

Add 6 and 1 to get 7.

$$\frac{14}{3}-\frac{7}{3}$$

Since \frac{14}{3} and \frac{7}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{14-7}{3}$$

Subtract 7 from 14 to get 7.

$$\frac{7}{3}$$

Factor

$$\frac{7}{3} = 2\frac{1}{3} = 2.3333333333333335$$
