Solve 2/4+1/4+2/8-1/2=

$$\frac { 2 } { 4 } + \frac { 1 } { 4 } + \frac { 2 } { 8 } - \frac { 1 } { 2 } =$$

Evaluate

$$\frac{1}{2}=0.5$$

Solution Steps

Since \frac{2}{4} and \frac{1}{4} have the same denominator, add them by adding their numerators.

$$\frac{2+1}{4}+\frac{2}{8}-\frac{1}{2}$$

Add 2 and 1 to get 3.

$$\frac{3}{4}+\frac{2}{8}-\frac{1}{2}$$

Reduce the fraction \frac{2}{8} to lowest terms by extracting and canceling out 2.

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

Since \frac{3}{4} and \frac{1}{4} have the same denominator, add them by adding their numerators.

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

Add 3 and 1 to get 4.

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

Divide 4 by 4 to get 1.

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

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

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

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

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

Subtract 1 from 2 to get 1.

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

Factor

$$\frac{1}{2} = 0.5$$
