Solve 21/6-15/6=

$$2 \frac { 1 } { 6 } - 1 \frac { 5 } { 6 } =$$

Evaluate

$$\frac{1}{3}\approx 0.333333333$$

Solution Steps

Multiply 2 and 6 to get 12.

$$\frac{12+1}{6}-\frac{1\times 6+5}{6}$$

Add 12 and 1 to get 13.

$$\frac{13}{6}-\frac{1\times 6+5}{6}$$

Multiply 1 and 6 to get 6.

$$\frac{13}{6}-\frac{6+5}{6}$$

Add 6 and 5 to get 11.

$$\frac{13}{6}-\frac{11}{6}$$

Since \frac{13}{6} and \frac{11}{6} have the same denominator, subtract them by subtracting their numerators.

$$\frac{13-11}{6}$$

Subtract 11 from 13 to get 2.

$$\frac{2}{6}$$

Reduce the fraction \frac{2}{6} to lowest terms by extracting and canceling out 2.

$$\frac{1}{3}$$

Factor

$$\frac{1}{3} = 0.3333333333333333$$
