Greetings!
"Andrew has one book that is 2 and 3/7 inches thick and a second book that is 3.56 ... to the nearest hundred?"...
To solve we have to turn the fraction into a decimal:
3/7=0.429
2+0.429
=2.49
Now you must add the numbers together:
2.49+3.56
=6.05
The total thickness of the books is 6.05 inches.
Hope this helps.
