6-133.

Change the mixed number into an improper fraction. Then change the fraction so it has a common denominator of 4. What Giant One can you use to do that?

$2\frac{1}{2}=\frac{5}{2}\;\;\;\;\;\;\;$

$\frac{5}{2}\left(\frac{2}{2}\right)=\frac{10}{4}$

Multiply the new fraction by the conversion factor to determine the number of feet. It might be helpful to think of ten-fourths as ten times one-fourth.

$10\left(\frac{1}{4}\right)\cdot \frac{\frac{1}{4}\text{ inch}}{1\text{ foot}} = 10\text{ feet}$

Now do the same thing with the other dimension to determine the length of Jessica's room.

10 feet by 17 feet
