Solve 83/2+53/2-3*1.5

$$8 \frac{ 3 }{ 2 } +5 \frac{ 3 }{ 2 } -3 \cdot 1.5$$

Evaluate

$$11.5$$

Solution Steps

Multiply 8 and 2 to get 16.

$$\frac{16+3}{2}+\frac{5\times 2+3}{2}-3\times 1.5$$

Add 16 and 3 to get 19.

$$\frac{19}{2}+\frac{5\times 2+3}{2}-3\times 1.5$$

Multiply 5 and 2 to get 10.

$$\frac{19}{2}+\frac{10+3}{2}-3\times 1.5$$

Add 10 and 3 to get 13.

$$\frac{19}{2}+\frac{13}{2}-3\times 1.5$$

Since \frac{19}{2} and \frac{13}{2} have the same denominator, add them by adding their numerators.

$$\frac{19+13}{2}-3\times 1.5$$

Add 19 and 13 to get 32.

$$\frac{32}{2}-3\times 1.5$$

Divide 32 by 2 to get 16.

$$16-3\times 1.5$$

Multiply 3 and 1.5 to get 4.5.

$$16-4.5$$

Subtract 4.5 from 16 to get 11.5.

$$11.5$$

Factor

$$\frac{23}{2} = 11\frac{1}{2} = 11.5$$
