A stack of 20 books is 24.6 inches tall. Irene guesses that each book is 10.23 inches tall. Explain how you know Irene's answer is not correct.
Each book is probably a different height, so she shouldn't try to guess how tall they are.
If you multiply 20 by 10.23, you would get a number much bigger than 24.6, so her estimate does not make sense.
Her decimal is in the wrong place by a power of 10.
The actual height of each book is 1.23 inches because 24.6 divided by 20 is 1.23.
