Solve +1/4+1/2-1=

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

Evaluate

$$-\frac{1}{4}=-0.25$$

Solution Steps

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

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

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

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

Add 1 and 2 to get 3.

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

Convert 1 to fraction \frac{4}{4}.

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

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

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

Subtract 4 from 3 to get -1.

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

Factor

$$-\frac{1}{4} = -0.25$$
