Solve 1-1/3-1/3-1/4

$$1 - \frac { 1 } { 3 } - \frac { 1 } { 3 } - \frac { 1 } { 4 }$$

Evaluate

$$\frac{1}{12}\approx 0.083333333$$

Solution Steps

Convert 1 to fraction \frac{3}{3}.

$$\frac{3}{3}-\frac{1}{3}-\frac{1}{3}-\frac{1}{4}$$

Since \frac{3}{3} and \frac{1}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{3-1}{3}-\frac{1}{3}-\frac{1}{4}$$

Subtract 1 from 3 to get 2.

$$\frac{2}{3}-\frac{1}{3}-\frac{1}{4}$$

Since \frac{2}{3} and \frac{1}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{2-1}{3}-\frac{1}{4}$$

Subtract 1 from 2 to get 1.

$$\frac{1}{3}-\frac{1}{4}$$

Least common multiple of 3 and 4 is 12. Convert \frac{1}{3} and \frac{1}{4} to fractions with denominator 12.

$$\frac{4}{12}-\frac{3}{12}$$

Since \frac{4}{12} and \frac{3}{12} have the same denominator, subtract them by subtracting their numerators.

$$\frac{4-3}{12}$$

Subtract 3 from 4 to get 1.

$$\frac{1}{12}$$

Factor

$$\frac{1}{2 ^ {2} \cdot 3} = 0.08333333333333333$$
