Solve 9-1+3div2+4

$$9 - 1 + 3 \div 2 + 4$$

Evaluate

$$\frac{27}{2}=13.5$$

Solution Steps

Subtract 1 from 9 to get 8.

$$8+\frac{3}{2}+4$$

Convert 8 to fraction \frac{16}{2}.

$$\frac{16}{2}+\frac{3}{2}+4$$

Since \frac{16}{2} and \frac{3}{2} have the same denominator, add them by adding their numerators.

$$\frac{16+3}{2}+4$$

Add 16 and 3 to get 19.

$$\frac{19}{2}+4$$

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

$$\frac{19}{2}+\frac{8}{2}$$

Since \frac{19}{2} and \frac{8}{2} have the same denominator, add them by adding their numerators.

$$\frac{19+8}{2}$$

Add 19 and 8 to get 27.

$$\frac{27}{2}$$

Factor

$$\frac{3 ^ {3}}{2} = 13\frac{1}{2} = 13.5$$
