No, Marcella is not correct. To determine if 60 books out of 100 is equal to 0.06 of the total books, we need to convert the percentage to a decimal.
If 60 books out of 100 total books equal 0.06 of the total books, then we can write this as:
60/100 = 0.06
However, when we simplify this, we see that 60/100 is actually equal to 0.60, not 0.06. So, Marcella's statement is not correct.
To model this, you can represent the total number of books Marcella read as 100. Then, calculate 0.06 of 100 by multiplying 100 by 0.06 to get 6. This shows that 0.06 of the total books is actually equal to 6 books, not 60.
