Solve 2/15+1/2-1/1

$$\frac { 2 } { 15 } + \frac { 1 } { 2 } - \frac { 1 } { 1 }$$

Evaluate

$$-\frac{11}{30}\approx -0.366666667$$

Solution Steps

Divide 1 by 1 to get 1.

$$\frac{2}{15}+\frac{1}{2}-1$$

Least common multiple of 15 and 2 is 30. Convert \frac{2}{15} and \frac{1}{2} to fractions with denominator 30.

$$\frac{4}{30}+\frac{15}{30}-1$$

Since \frac{4}{30} and \frac{15}{30} have the same denominator, add them by adding their numerators.

$$\frac{4+15}{30}-1$$

Add 4 and 15 to get 19.

$$\frac{19}{30}-1$$

Convert 1 to fraction \frac{30}{30}.

$$\frac{19}{30}-\frac{30}{30}$$

Since \frac{19}{30} and \frac{30}{30} have the same denominator, subtract them by subtracting their numerators.

$$\frac{19-30}{30}$$

Subtract 30 from 19 to get -11.

$$-\frac{11}{30}$$

Factor

$$-\frac{11}{30} = -0.36666666666666664$$
