Jonathan and Byron both have comic book collection the number of books in the collection form a ratio 4:9 of Jonathan's to Byron

worty [1.4K]

Since the ratio is 4:9 your trying to find the sum. What I mean is that if it's 4 to 9, whats 20+9? =29. Do the same for 4. 20+4= 24. Now you find the difference in order to find how much does Byron have compared to Jonathan. So 29-24= 5
