Solve 51/2+21/2=

$$5 \frac { 1 } { 2 } + 2 \frac { 1 } { 2 } =$$

Evaluate

$$8$$

Solution Steps

Multiply 5 and 2 to get 10.

$$\frac{10+1}{2}+\frac{2\times 2+1}{2}$$

Add 10 and 1 to get 11.

$$\frac{11}{2}+\frac{2\times 2+1}{2}$$

Multiply 2 and 2 to get 4.

$$\frac{11}{2}+\frac{4+1}{2}$$

Add 4 and 1 to get 5.

$$\frac{11}{2}+\frac{5}{2}$$

Since \frac{11}{2} and \frac{5}{2} have the same denominator, add them by adding their numerators.

$$\frac{11+5}{2}$$

Add 11 and 5 to get 16.

$$\frac{16}{2}$$

Divide 16 by 2 to get 8.

$$8$$

Factor

$$2^{3}$$
