Final Answer:
The given information expressed in the form 1:n is "O Rei is in the ratio 5:15."
Step-by-step explanation:
To express the given information in the form 1:n, where O Rei is in the ratio 5:15, we can simplify the ratio by dividing both parts by their greatest common factor, which is 5. The simplified ratio becomes 1:3. This means that for every 1 unit of O Rei, there are 3 units in the given context. In this case, it implies that if O Rei has a quantity of 5, the corresponding quantity in the ratio is 15 (5 multiplied by 3), maintaining the original proportion.
The ratio 1:3 serves as a concise representation of the relationship between the quantities, offering a clear understanding of the proportionality between O Rei and the other entity in the given context. It's a useful mathematical tool for expressing relationships and comparisons, providing a straightforward way to convey the relative sizes or amounts of different elements. Therefore, expressing the given information as 1:3 captures the essence of the ratio and allows for easy interpretation of the relationship between O Rei and the associated quantity in the specified ratio.
