Solve 83/2+5*3/2-3*1.5=

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

Evaluate

$$12.5$$

Solution Steps

Multiply 8 and 2 to get 16.

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

Add 16 and 3 to get 19.

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

Express 5\times \frac{3}{2} as a single fraction.

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

Multiply 5 and 3 to get 15.

$$\frac{19}{2}+\frac{15}{2}-3\times 1.5$$

Since \frac{19}{2} and \frac{15}{2} have the same denominator, add them by adding their numerators.

$$\frac{19+15}{2}-3\times 1.5$$

Add 19 and 15 to get 34.

$$\frac{34}{2}-3\times 1.5$$

Divide 34 by 2 to get 17.

$$17-3\times 1.5$$

Multiply 3 and 1.5 to get 4.5.

$$17-4.5$$

Subtract 4.5 from 17 to get 12.5.

$$12.5$$

Factor

$$\frac{5 ^ {2}}{2} = 12\frac{1}{2} = 12.5$$
