To determine the amount of content for each section of the book, we first need to find the individual ratios of the core Java and advanced Java sections.

The total ratio can be calculated by adding the ratios of the two sections:

core Java ratio + advanced Java ratio = 7 + 3 = 10

Now, let's calculate the proportion of the book that each section represents:

core Java proportion = (core Java ratio / total ratio) * total pages
advanced Java proportion = (advanced Java ratio / total ratio) * total pages

Substituting the given values:

core Java proportion = (7 / 10) * 450 = 7 * 45 = 315 pages
advanced Java proportion = (3 / 10) * 450 = 3 * 45 = 135 pages

Therefore, to make a book of 450 pages with a core Java to advanced Java ratio of 7:3, you would need 315 pages of core Java content and 135 pages of advanced Java content.
