Solve (1-1/2):(1+1/2)=

$$( 1 - \frac { 1 } { 2 } ) : ( 1 + \frac { 1 } { 2 } ) =$$

Evaluate

$$\frac{1}{3}\approx 0.333333333$$

Solution Steps

Convert 1 to fraction \frac{2}{2}.

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

Since \frac{2}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 1 from 2 to get 1.

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

Convert 1 to fraction \frac{2}{2}.

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

Since \frac{2}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.

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

Add 2 and 1 to get 3.

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

Divide \frac{1}{2} by \frac{3}{2} by multiplying \frac{1}{2} by the reciprocal of \frac{3}{2}.

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

Multiply \frac{1}{2} times \frac{2}{3} by multiplying numerator times numerator and denominator times denominator.

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

Cancel out 2 in both numerator and denominator.

$$\frac{1}{3}$$

Factor

$$\frac{1}{3} = 0.3333333333333333$$
