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

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

Evaluate

$$\frac{7}{4}=1.75$$

Solution Steps

Anything divided by one gives itself.

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

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

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

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

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

Add 1 and 4 to get 5.

$$\frac{5}{2}-\frac{3}{4}$$

Least common multiple of 2 and 4 is 4. Convert \frac{5}{2} and \frac{3}{4} to fractions with denominator 4.

$$\frac{10}{4}-\frac{3}{4}$$

Since \frac{10}{4} and \frac{3}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{10-3}{4}$$

Subtract 3 from 10 to get 7.

$$\frac{7}{4}$$

Factor

$$\frac{7}{2 ^ {2}} = 1\frac{3}{4} = 1.75$$
