Simplify 2/(3x)+(3x)/4

$\frac{2}{3 x} + \frac{3 x}{4}$

Step 1

To write $\frac{2}{3 x}$ as a fraction with a common denominator, multiply by $\frac{4}{4}$ .

$\frac{2}{3 x} \cdot \frac{4}{4} + \frac{3 x}{4}$

Step 2

To write $\frac{3 x}{4}$ as a fraction with a common denominator, multiply by $\frac{3 x}{3 x}$ .

$\frac{2}{3 x} \cdot \frac{4}{4} + \frac{3 x}{4} \cdot \frac{3 x}{3 x}$

Step 3

Write each expression with a common denominator of $12 x$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{2}{3 x}$ by $\frac{4}{4}$ .

$\frac{2 \cdot 4}{3 x \cdot 4} + \frac{3 x}{4} \cdot \frac{3 x}{3 x}$

Multiply $4$ by $3$ .

$\frac{2 \cdot 4}{12 x} + \frac{3 x}{4} \cdot \frac{3 x}{3 x}$

Multiply $\frac{3 x}{4}$ by $\frac{3 x}{3 x}$ .

$\frac{2 \cdot 4}{12 x} + \frac{3 x (3 x)}{4 (3 x)}$

Multiply $3$ by $4$ .

$\frac{2 \cdot 4}{12 x} + \frac{3 x (3 x)}{12 x}$

Step 4

Combine the numerators over the common denominator.

$\frac{2 \cdot 4 + 3 x (3 x)}{12 x}$

Step 5

Simplify the numerator.

Multiply $2$ by $4$ .

$\frac{8 + 3 x (3 x)}{12 x}$

Rewrite using the commutative property of multiplication.

$\frac{8 + 3 \cdot 3 x \cdot x}{12 x}$
