Solve 1+1/2+4*1/2

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

Evaluate

$$\frac{7}{2}=3.5$$

Solution Steps

Convert 1 to fraction \frac{2}{2}.

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

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

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

Add 2 and 1 to get 3.

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

Multiply 4 and \frac{1}{2} to get \frac{4}{2}.

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

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

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

Add 3 and 4 to get 7.

$$\frac{7}{2}$$

Factor

$$\frac{7}{2} = 3\frac{1}{2} = 3.5$$
