Solve 1/2+1/4-3/8=

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

Evaluate

$$\frac{3}{8}=0.375$$

Solution Steps

Least common multiple of 2 and 4 is 4. Convert \frac{1}{2} and \frac{1}{4} to fractions with denominator 4.

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

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

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

Add 2 and 1 to get 3.

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

Least common multiple of 4 and 8 is 8. Convert \frac{3}{4} and \frac{3}{8} to fractions with denominator 8.

$$\frac{6}{8}-\frac{3}{8}$$

Since \frac{6}{8} and \frac{3}{8} have the same denominator, subtract them by subtracting their numerators.

$$\frac{6-3}{8}$$

Subtract 3 from 6 to get 3.

$$\frac{3}{8}$$

Factor

$$\frac{3}{2 ^ {3}} = 0.375$$
