Answer: They can fit 9 thick books into the bookshelf
Step-by-step explanation: So I like putting fractions into decimals.
1 3/5 = 1.6 and 14 1/2 = 14.5
I got .6 because 1/5 is 20%, 2/5 is 40%, (3/5 is 60%), and it keeps going.
Now that we have that all we have to do is 14.5 divided by 1.6
14.5 divided by 1.6 = 9.06
Hope this helps!
