Solve 41/2+51/2

$$4 \frac { 1 } { 2 } + 5 \frac { 1 } { 2 }$$

Evaluate

$$10$$

Solution Steps

Multiply 4 and 2 to get 8.

$$\frac{8+1}{2}+\frac{5\times 2+1}{2}$$

Add 8 and 1 to get 9.

$$\frac{9}{2}+\frac{5\times 2+1}{2}$$

Multiply 5 and 2 to get 10.

$$\frac{9}{2}+\frac{10+1}{2}$$

Add 10 and 1 to get 11.

$$\frac{9}{2}+\frac{11}{2}$$

Since \frac{9}{2} and \frac{11}{2} have the same denominator, add them by adding their numerators.

$$\frac{9+11}{2}$$

Add 9 and 11 to get 20.

$$\frac{20}{2}$$

Divide 20 by 2 to get 10.

$$10$$

Factor

$$2\times 5$$
