Solve (141/2-31/2):3

$$( 14 \frac { 1 } { 2 } - 3 \frac { 1 } { 2 } ) : 3$$

Evaluate

$$\frac{11}{3}\approx 3.666666667$$

Solution Steps

Multiply 14 and 2 to get 28.

$$\frac{\frac{28+1}{2}-\frac{3\times 2+1}{2}}{3}$$

Add 28 and 1 to get 29.

$$\frac{\frac{29}{2}-\frac{3\times 2+1}{2}}{3}$$

Multiply 3 and 2 to get 6.

$$\frac{\frac{29}{2}-\frac{6+1}{2}}{3}$$

Add 6 and 1 to get 7.

$$\frac{\frac{29}{2}-\frac{7}{2}}{3}$$

Since \frac{29}{2} and \frac{7}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{\frac{29-7}{2}}{3}$$

Subtract 7 from 29 to get 22.

$$\frac{\frac{22}{2}}{3}$$

Divide 22 by 2 to get 11.

$$\frac{11}{3}$$

Factor

$$\frac{11}{3} = 3\frac{2}{3} = 3.6666666666666665$$
