Solve 21/6-1/4

$$2 \frac { 1 } { 6 } - \frac { 1 } { 4 }$$

Evaluate

$$\frac{23}{12}\approx 1.916666667$$

Solution Steps

Multiply 2 and 6 to get 12.

$$\frac{12+1}{6}-\frac{1}{4}$$

Add 12 and 1 to get 13.

$$\frac{13}{6}-\frac{1}{4}$$

Least common multiple of 6 and 4 is 12. Convert \frac{13}{6} and \frac{1}{4} to fractions with denominator 12.

$$\frac{26}{12}-\frac{3}{12}$$

Since \frac{26}{12} and \frac{3}{12} have the same denominator, subtract them by subtracting their numerators.

$$\frac{26-3}{12}$$

Subtract 3 from 26 to get 23.

$$\frac{23}{12}$$

Factor

$$\frac{23}{2 ^ {2} \cdot 3} = 1\frac{11}{12} = 1.9166666666666667$$
