Answer 1

Answer: $1 \frac{2}{12}\ ft$

Step-by-step explanation:

The height of Denise castle is  $1 \frac{7}{12}=\frac{12\times 1+7}{12}=\frac{19}{12}\ ft$

height of her sister  $\frac{5}{12}\ ft$

Difference between the height of the castle

$\Rightarrow \frac{19}{12}-\frac{5}{12}=\frac{14}{12}$

In mixed fraction it is $\frac{14}{12}\ or\ 1 \frac{2}{12}\ ft$
