i am really confused on what numbers to use to get the calculations on the 13 ratios

To perform calculations involving ratios, you need to have specific numbers that represent the quantities being compared. Ratios compare two or more values and can be expressed in different formats, such as 3:4, 3/4, or 0.75.

To determine the numbers needed for calculations involving 13 ratios, you'll typically require two quantities for each ratio. For example, if you have a ratio of 3:4, which describes the relationship between two quantities, you would need values to represent those quantities.

To clarify further, let's assume you have a total of 13 ratios. This means you'll need 26 specific quantities—one for each value being compared in the ratio. Each of these quantities will be represented in relation to another quantity. It's important to know the purpose or context of these ratios in order to determine the appropriate numbers.

Once you have the required numbers, you can perform various calculations, such as finding the average ratio, totaling the ratios, or comparing the values in different ways.
