Simplify 3n-1/2*0.3n

$3 n - \frac{1}{2} \cdot 0.3 n$

Step 1

Simplify each term.

Multiply $- \frac{1}{2} (0.3 n)$ .

Multiply $0.3$ by $- 1$ .

$3 n - 0.3 (\frac{1}{2}) n$

Combine $- 0.3$ and $\frac{1}{2}$ .

$3 n + \frac{- 0.3}{2} n$

Combine $\frac{- 0.3}{2}$ and $n$ .

$3 n + \frac{- 0.3 n}{2}$

$3 n + \frac{- 0.3 n}{2}$

Move the negative in front of the fraction.

$3 n - \frac{(0.3) n}{2}$

Factor $0.3$ out of $0.3 n$ .

$3 n - \frac{0.3 (n)}{2}$

Factor $2$ out of $2$ .

$3 n - \frac{0.3 (n)}{2 (1)}$

Separate fractions.

$3 n - (\frac{0.3}{2} \cdot \frac{n}{1})$

Divide $0.3$ by $2$ .

$3 n - (0.15 \frac{n}{1})$

Divide $n$ by $1$ .

$3 n - (0.15 n)$

Multiply $0.15$ by $- 1$ .

$3 n - 0.15 n$

$3 n - 0.15 n$

Step 2

Subtract $0.15 n$ from $3 n$ .

$2.85 n$
