Alice has 6 more books than Steven. Clara has two times as many books as Steven. If Clara has 20 books, how many more books does Clara have than Alice?
How many books does Steven have? ** Steven has 20/2 = <<20/2=10>>10 books
How many books does Alice have? ** Alice has 10+6 = <<10+6=16>>16 books
How many more books does Clara have than Alice? ** Clara has 20-16 = <<20-16=4>>4 more books than Alice
