Alright, lets get started.
A squirrel is 1.1 feet tall.
The squirrel shrinks to 1/10 of its height
So, we need to do 1/10 of the squirrel's height for knowing how much it shrinks.
So, the amount squirrel shrinks = [tex]1.1*\frac{1}{10} = 0.11[/tex] feet
So, its current height will be = [tex]1.1 - 0.11 = 0.99[/tex] feet
It means squirrel is now 0.99 feet long. : Answer
Hope it will help :)
