Final answer:
To fill in missing values in a ratio table, one must use fundamental ratio properties, handle equivalencies, ensure unit consistency, and use calculations for relative frequencies and cumulative frequencies. Cross-multiplication often aids in solving proportions.
Step-by-step explanation:
To find the missing values in a ratio table and write equivalent ratios, one must understand how ratios express a relationship between two quantities. For example, if you have a proportion such as 1/20=1/5.5, you can find an equivalent ratio by cross-multiplying and solving for the missing term. In a table context, aligning the known values and applying the fundamental properties of ratios can help fill in gaps where needed. If we need to find a cumulative relative frequency, we add up all the relative frequencies up to the current point. When dealing with tables where entries multiply to a specific number, using reciprocals and understanding the relationships between numbers (e.g., reciprocal of 8 is '1.25-like') is essential. Being meticulous with units and ensuring correct equation usage is also crucial, as shown in instructions like organizing data, setting equal ratios, and forming proportions such as Length=1/50=0.5/5 and Width=w/30=0.5/.
When rounding off values to, say, two decimal places, one must follow standard rounding rules. Lastly, analyzing data typically involves entering data into a calculator or computer to aid in calculations, like obtaining a linear equation and rounding it accordingly.
