Solve 15-5-3/2+8

$$15-5- \frac{ 3 }{ 2 } +8$$

Evaluate

$$\frac{33}{2}=16.5$$

Solution Steps

Subtract 5 from 15 to get 10.

$$10-\frac{3}{2}+8$$

Convert 10 to fraction \frac{20}{2}.

$$\frac{20}{2}-\frac{3}{2}+8$$

Since \frac{20}{2} and \frac{3}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{20-3}{2}+8$$

Subtract 3 from 20 to get 17.

$$\frac{17}{2}+8$$

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

$$\frac{17}{2}+\frac{16}{2}$$

Since \frac{17}{2} and \frac{16}{2} have the same denominator, add them by adding their numerators.

$$\frac{17+16}{2}$$

Add 17 and 16 to get 33.

$$\frac{33}{2}$$

Factor

$$\frac{3 \cdot 11}{2} = 16\frac{1}{2} = 16.5$$
