In order to solve this question, we need to compute the following operation:

$2(1)/(2)yard\text{ - \lparen2feet+ 8inches\rparen}$

or equivalently,

$(5)/(2)\text{ yards- \lparen2feet+ 8inches\rparen}$

However, we need to convert first the yards and feet to inches. Since 1 yard has 36 inches, we have

$\begin{gathered} (5)/(2)\text{ yards=}(5)/(2)yard(\frac{36\text{ inches}}{1\text{ yards}}) \\ (5)/(2)\text{ yards=90 inches} \end{gathered}$

Similarly, since 1 feet has 12 inches, we get

$\begin{gathered} 2\text{ feet = 2feet\lparen}(12inches)/(1feet)) \\ 2\text{ feet = 24inches} \end{gathered}$

Then, our first operation is equivalent to

which gives

Then, How many inches of ribbon did Anais use to trim the curtains? Answer: Anais used 70 inches of ribbon.
