Write $2 \sqrt{3}$ as a fraction with denominator $1$ .

$\frac{2 \sqrt{3}}{1} - \frac{10 \sqrt{3}}{3} + \sqrt{3}$

Multiply $\frac{2 \sqrt{3}}{1}$ by $\frac{3}{3}$ .

$\frac{2 \sqrt{3}}{1} \cdot \frac{3}{3} - \frac{10 \sqrt{3}}{3} + \sqrt{3}$

Multiply $\frac{2 \sqrt{3}}{1}$ by $\frac{3}{3}$ .

$\frac{2 \sqrt{3} \cdot 3}{3} - \frac{10 \sqrt{3}}{3} + \sqrt{3}$

Write $\sqrt{3}$ as a fraction with denominator $1$ .

$\frac{2 \sqrt{3} \cdot 3}{3} - \frac{10 \sqrt{3}}{3} + \frac{\sqrt{3}}{1}$

Multiply $\frac{\sqrt{3}}{1}$ by $\frac{3}{3}$ .

$\frac{2 \sqrt{3} \cdot 3}{3} - \frac{10 \sqrt{3}}{3} + \frac{\sqrt{3}}{1} \cdot \frac{3}{3}$

Multiply $\frac{\sqrt{3}}{1}$ by $\frac{3}{3}$ .

$\frac{2 \sqrt{3} \cdot 3}{3} - \frac{10 \sqrt{3}}{3} + \frac{\sqrt{3} \cdot 3}{3}$

Step 3

Combine the numerators over the common denominator.

$\frac{2 \sqrt{3} \cdot 3 - 10 \sqrt{3} + \sqrt{3} \cdot 3}{3}$

Step 4

Simplify each term.

Multiply $3$ by $2$ .

$\frac{6 \sqrt{3} - 10 \sqrt{3} + \sqrt{3} \cdot 3}{3}$

Move $3$ to the left of $\sqrt{3}$ .

$\frac{6 \sqrt{3} - 10 \sqrt{3} + 3 \sqrt{3}}{3}$

Step 5

Simplify by adding terms.

Subtract $10 \sqrt{3}$ from $6 \sqrt{3}$ .

$\frac{- 4 \sqrt{3} + 3 \sqrt{3}}{3}$

Add $- 4 \sqrt{3}$ and $3 \sqrt{3}$ .

$\frac{- \sqrt{3}}{3}$

Move the negative in front of the fraction.

$- \frac{\sqrt{3}}{3}$

Step 6

The result can be shown in multiple forms.

Exact Form:

$- \frac{\sqrt{3}}{3}$

Decimal Form:

$- 0.57735026 \dots$
