Evaluate ( square root of 3)/( square root of 12)

$\frac{\sqrt{3}}{\sqrt{12}}$

Step 1

Combine $\sqrt{3}$ and $\sqrt{12}$ into a single radical.

$\sqrt{\frac{3}{12}}$

Step 2

Cancel the common factor of $3$ and $12$ .

Factor $3$ out of $3$ .

$\sqrt{\frac{3 (1)}{12}}$

Cancel the common factors.

Factor $3$ out of $12$ .

$\sqrt{\frac{3 \cdot 1}{3 \cdot 4}}$

Cancel the common factor.

$\sqrt{\frac{3 \cdot 1}{3 \cdot 4}}$

Rewrite the expression.

$\sqrt{\frac{1}{4}}$

Step 3

Rewrite $\sqrt{\frac{1}{4}}$ as $\frac{\sqrt{1}}{\sqrt{4}}$ .

$\frac{\sqrt{1}}{\sqrt{4}}$

Step 4

Any root of $1$ is $1$ .

$\frac{1}{\sqrt{4}}$

Step 5

Simplify the denominator.

Rewrite $4$ as $2^{2}$ .

$\frac{1}{\sqrt{2^{2}}}$

Pull terms out from under the radical, assuming positive real numbers.

$\frac{1}{2}$

Step 6

The result can be shown in multiple forms.

Exact Form:

$\frac{1}{2}$

Decimal Form:

$0.5$
