Solve 1/8-1/2+0.5

$$\frac{ 1 }{ 8 } - \frac{ 1 }{ 2 } +0.5$$

Evaluate

$$0.125$$

Solution Steps

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

$$\frac{1}{8}-\frac{4}{8}+0.5$$

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

$$\frac{1-4}{8}+0.5$$

Subtract 4 from 1 to get -3.

$$-\frac{3}{8}+0.5$$

Convert decimal number 0.5 to fraction \frac{5}{10}. Reduce the fraction \frac{5}{10} to lowest terms by extracting and canceling out 5.

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

Least common multiple of 8 and 2 is 8. Convert -\frac{3}{8} and \frac{1}{2} to fractions with denominator 8.

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

Since -\frac{3}{8} and \frac{4}{8} have the same denominator, add them by adding their numerators.

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

Add -3 and 4 to get 1.

$$\frac{1}{8}$$

Factor

$$\frac{1}{2 ^ {3}} = 0.125$$
