$\frac{40}{x} \cdot \frac{x (5.5)}{5}$

Step 1

Move $5.5$ to the left of $x$ .

$\frac{40}{x} \cdot \frac{5.5 x}{5}$

Step 2

Factor $5.5$ out of $5.5 x$ .

$\frac{40}{x} \cdot \frac{5.5 (x)}{5}$

Step 3

Factor $5$ out of $5$ .

$\frac{40}{x} \cdot \frac{5.5 (x)}{5 (1)}$

Step 4

Separate fractions.

$\frac{40}{x} \cdot \frac{5.5}{5} \cdot \frac{x}{1}$

Step 5

Divide $5.5$ by $5$ .

$\frac{40}{x} \cdot (1.1 (\frac{x}{1}))$

Step 6

Divide $x$ by $1$ .

$\frac{40}{x} \cdot (1.1 x)$

Step 7

Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.

$x, 1$

Step 8

The LCM of one and any expression is the expression.

$x$
