Solve 21/2+31/2

$$2 \frac { 1 } { 2 } + 3 \frac { 1 } { 2 }$$

Evaluate

$$6$$

Solution Steps

Multiply 2 and 2 to get 4.

$$\frac{4+1}{2}+\frac{3\times 2+1}{2}$$

Add 4 and 1 to get 5.

$$\frac{5}{2}+\frac{3\times 2+1}{2}$$

Multiply 3 and 2 to get 6.

$$\frac{5}{2}+\frac{6+1}{2}$$

Add 6 and 1 to get 7.

$$\frac{5}{2}+\frac{7}{2}$$

Since \frac{5}{2} and \frac{7}{2} have the same denominator, add them by adding their numerators.

$$\frac{5+7}{2}$$

Add 5 and 7 to get 12.

$$\frac{12}{2}$$

Divide 12 by 2 to get 6.

$$6$$

Factor

$$2\times 3$$
