Solve 1/5-11/2

$$\frac { 1 } { 5 } - 1 \frac { 1 } { 2 }$$

Evaluate

$$-\frac{13}{10}=-1.3$$

Solution Steps

Multiply 1 and 2 to get 2.

$$\frac{1}{5}-\frac{2+1}{2}$$

Add 2 and 1 to get 3.

$$\frac{1}{5}-\frac{3}{2}$$

Least common multiple of 5 and 2 is 10. Convert \frac{1}{5} and \frac{3}{2} to fractions with denominator 10.

$$\frac{2}{10}-\frac{15}{10}$$

Since \frac{2}{10} and \frac{15}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{2-15}{10}$$

Subtract 15 from 2 to get -13.

$$-\frac{13}{10}$$

Factor

$$-\frac{13}{10} = -1\frac{3}{10} = -1.3$$
