Solve 41/2-51/2

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

Evaluate

$$-1$$

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, subtract them by subtracting their numerators.

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

Subtract 11 from 9 to get -2.

$$\frac{-2}{2}$$

Divide -2 by 2 to get -1.

$$-1$$

Factor

$$-1$$
