Solve 1/2-1/8+1/8

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

Evaluate

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

Solution Steps

Least common multiple of 2 and 8 is 8. Convert \frac{1}{2} and \frac{1}{8} to fractions with denominator 8.

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

Since \frac{4}{8} and \frac{1}{8} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 1 from 4 to get 3.

$$\frac{3}{8}+\frac{1}{8}$$

Since \frac{3}{8} and \frac{1}{8} have the same denominator, add them by adding their numerators.

$$\frac{3+1}{8}$$

Add 3 and 1 to get 4.

$$\frac{4}{8}$$

Reduce the fraction \frac{4}{8} to lowest terms by extracting and canceling out 4.

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

Factor

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