Solve 41/2-31/2

$$4 \frac { 1 } { 2 } - 3 \frac { 1 } { 2 }$$

Evaluate

$$1$$

Solution Steps

Multiply 4 and 2 to get 8.

$$\frac{8+1}{2}-\frac{3\times 2+1}{2}$$

Add 8 and 1 to get 9.

$$\frac{9}{2}-\frac{3\times 2+1}{2}$$

Multiply 3 and 2 to get 6.

$$\frac{9}{2}-\frac{6+1}{2}$$

Add 6 and 1 to get 7.

$$\frac{9}{2}-\frac{7}{2}$$

Since \frac{9}{2} and \frac{7}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{9-7}{2}$$

Subtract 7 from 9 to get 2.

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

Divide 2 by 2 to get 1.

$$1$$

Factor

$$1$$
