Transcript text: Select all the expressions that represent the difference of the length-to is the width of rectangle $A$.
$\frac{w+5}{w}-\frac{w+1}{2 w}$
$\frac{4}{3 w}$
$\frac{w+5}{w+1}-\frac{w}{2 w}$
$\frac{w+9}{2 w}$
$\frac{w+11}{2 w}$
Solution
Solution Steps
Step 1: Find the length-to-width ratio of rectangle A
The length of rectangle A is $w + 5$, and the width is $w$. The length-to-width ratio of rectangle A is $\frac{w+5}{w}$.
Step 2: Find the length-to-width ratio of rectangle B
The length of rectangle B is $w + 1$, and the width is $2w$. The length-to-width ratio of rectangle B is $\frac{w+1}{2w}$.
Step 3: Find the difference between the length-to-width ratios
The difference between the length-to-width ratios is $\frac{w+5}{w} - \frac{w+1}{2w}$.
Step 4: Simplify the difference
To subtract the two fractions, find a common denominator. In this case, the common denominator is $2w$. Multiply the numerator and denominator of the first fraction by 2:
$\frac{2(w+5)}{2w} - \frac{w+1}{2w} = \frac{2w+10}{2w} - \frac{w+1}{2w}$. Now subtract the numerators:
$\frac{(2w+10)-(w+1)}{2w} = \frac{2w+10-w-1}{2w} = \frac{w+9}{2w}$.
Final Answer:
The expressions that represent the difference are $\frac{w+5}{w} - \frac{w+1}{2w}$ and $\frac{w+9}{2w}$.
