Solve 8/11-11/2=

$$\frac { 8 } { 11 } - 1 \frac { 1 } { 2 } =$$

Evaluate

$$-\frac{17}{22}\approx -0.772727273$$

Solution Steps

Multiply 1 and 2 to get 2.

$$\frac{8}{11}-\frac{2+1}{2}$$

Add 2 and 1 to get 3.

$$\frac{8}{11}-\frac{3}{2}$$

Least common multiple of 11 and 2 is 22. Convert \frac{8}{11} and \frac{3}{2} to fractions with denominator 22.

$$\frac{16}{22}-\frac{33}{22}$$

Since \frac{16}{22} and \frac{33}{22} have the same denominator, subtract them by subtracting their numerators.

$$\frac{16-33}{22}$$

Subtract 33 from 16 to get -17.

$$-\frac{17}{22}$$

Factor

$$-\frac{17}{22} = -0.7727272727272727$$
