Solve 3/6+1/4-2/1

$$\frac{ 3 }{ 6 } + \frac{ 1 }{ 4 } - \frac{ 2 }{ 1 }$$

Evaluate

$$-\frac{5}{4}=-1.25$$

Solution Steps

Reduce the fraction \frac{3}{6} to lowest terms by extracting and canceling out 3.

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

Least common multiple of 2 and 4 is 4. Convert \frac{1}{2} and \frac{1}{4} to fractions with denominator 4.

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

Since \frac{2}{4} and \frac{1}{4} have the same denominator, add them by adding their numerators.

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

Add 2 and 1 to get 3.

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

Anything divided by one gives itself.

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

Convert 2 to fraction \frac{8}{4}.

$$\frac{3}{4}-\frac{8}{4}$$

Since \frac{3}{4} and \frac{8}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{3-8}{4}$$

Subtract 8 from 3 to get -5.

$$-\frac{5}{4}$$

Factor

$$-\frac{5}{4} = -1\frac{1}{4} = -1.25$$
