Solve 131/2-44/2=

$$13 \frac { 1 } { 2 } - 4 \frac { 4 } { 2 } =$$

Evaluate

$$\frac{15}{2}=7.5$$

Solution Steps

Multiply 13 and 2 to get 26.

$$\frac{26+1}{2}-\frac{4\times 2+4}{2}$$

Add 26 and 1 to get 27.

$$\frac{27}{2}-\frac{4\times 2+4}{2}$$

Multiply 4 and 2 to get 8.

$$\frac{27}{2}-\frac{8+4}{2}$$

Add 8 and 4 to get 12.

$$\frac{27}{2}-\frac{12}{2}$$

Since \frac{27}{2} and \frac{12}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{27-12}{2}$$

Subtract 12 from 27 to get 15.

$$\frac{15}{2}$$

Factor

$$\frac{3 \cdot 5}{2} = 7\frac{1}{2} = 7.5$$
