Solve 1/2+2/1-8/4=

$$\frac{ 1 }{ 2 } + \frac{ 2 }{ 1 } - \frac{ 8 }{ 4 } =$$

Evaluate

$$\frac{1}{2}=0.5$$

Solution Steps

Anything divided by one gives itself.

$$\frac{1}{2}+2-\frac{8}{4}$$

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

$$\frac{1}{2}+\frac{4}{2}-\frac{8}{4}$$

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

$$\frac{1+4}{2}-\frac{8}{4}$$

Add 1 and 4 to get 5.

$$\frac{5}{2}-\frac{8}{4}$$

Divide 8 by 4 to get 2.

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

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

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

Since \frac{5}{2} and \frac{4}{2} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 4 from 5 to get 1.

$$\frac{1}{2}$$

Factor

$$\frac{1}{2} = 0.5$$
