Solve (3/4-1/2)*3

$$( \frac { 3 } { 4 } - \frac { 1 } { 2 } ) \cdot 3$$

Evaluate

$$\frac{3}{4}=0.75$$

Solution Steps

Least common multiple of 4 and 2 is 4. Convert \frac{3}{4} and \frac{1}{2} to fractions with denominator 4.

$$\left(\frac{3}{4}-\frac{2}{4}\right)\times 3$$

Since \frac{3}{4} and \frac{2}{4} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 2 from 3 to get 1.

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

Multiply \frac{1}{4} and 3 to get \frac{3}{4}.

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

Factor

$$\frac{3}{2 ^ {2}} = 0.75$$
