Solve 3/2+7/4-5/2=

$$\frac{ 3 }{ 2 } + \frac{ 7 }{ 4 } - \frac{ 5 }{ 2 } =$$

Evaluate

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

Solution Steps

Least common multiple of 2 and 4 is 4. Convert \frac{3}{2} and \frac{7}{4} to fractions with denominator 4.

$$\frac{6}{4}+\frac{7}{4}-\frac{5}{2}$$

Since \frac{6}{4} and \frac{7}{4} have the same denominator, add them by adding their numerators.

$$\frac{6+7}{4}-\frac{5}{2}$$

Add 6 and 7 to get 13.

$$\frac{13}{4}-\frac{5}{2}$$

Least common multiple of 4 and 2 is 4. Convert \frac{13}{4} and \frac{5}{2} to fractions with denominator 4.

$$\frac{13}{4}-\frac{10}{4}$$

Since \frac{13}{4} and \frac{10}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{13-10}{4}$$

Subtract 10 from 13 to get 3.

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

Factor

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