Solve 11/2-7/8

$$1 \frac { 1 } { 2 } - \frac { 7 } { 8 }$$

Evaluate

$$\frac{5}{8}=0.625$$

Solution Steps

Multiply 1 and 2 to get 2.

$$\frac{2+1}{2}-\frac{7}{8}$$

Add 2 and 1 to get 3.

$$\frac{3}{2}-\frac{7}{8}$$

Least common multiple of 2 and 8 is 8. Convert \frac{3}{2} and \frac{7}{8} to fractions with denominator 8.

$$\frac{12}{8}-\frac{7}{8}$$

Since \frac{12}{8} and \frac{7}{8} have the same denominator, subtract them by subtracting their numerators.

$$\frac{12-7}{8}$$

Subtract 7 from 12 to get 5.

$$\frac{5}{8}$$

Factor

$$\frac{5}{2 ^ {3}} = 0.625$$
