Solve 1div2*3-4+5

$$1 \div 2 \times 3-4+5$$

Evaluate

$$\frac{5}{2}=2.5$$

Solution Steps

Multiply \frac{1}{2} and 3 to get \frac{3}{2}.

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

Convert 4 to fraction \frac{8}{2}.

$$\frac{3}{2}-\frac{8}{2}+5$$

Since \frac{3}{2} and \frac{8}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{3-8}{2}+5$$

Subtract 8 from 3 to get -5.

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

Convert 5 to fraction \frac{10}{2}.

$$-\frac{5}{2}+\frac{10}{2}$$

Since -\frac{5}{2} and \frac{10}{2} have the same denominator, add them by adding their numerators.

$$\frac{-5+10}{2}$$

Add -5 and 10 to get 5.

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

Factor

$$\frac{5}{2} = 2\frac{1}{2} = 2.5$$
