A Java book is comprised of two sections core and advanced Java in the ratio 7:3. How much of each type of content will be needed to make a book of 450 pages?
To find out how much content is needed for each section of the book, we first need to determine the number of pages allocated to each section based on the given ratio.
Step 1: Calculate the total ratio
The total ratio is the sum of the individual ratios: 7 + 3 = 10.
Step 2: Determine the fraction of pages for each section
For core Java: (7/10) * 450 = 315 pages.
For advanced Java: (3/10) * 450 = 135 pages.
Therefore, to make a book of 450 pages with a ratio of 7:3 for core and advanced Java respectively, you would need 315 pages of core Java content and 135 pages of advanced Java content.
let the number of pages be 7x and 3x
7x + 3x = 450
