4. Look at the ratios below. Write an example of how these ratios could be used in a part-to-part and part-to -whole scenario. a) 1:4 b) 75:600

## Step 1: Understanding Part-to-Part and Part-to-Whole Ratios### A part-to-part ratio compares one part of a whole to another part, while a part-to-whole ratio compares one part to the entire whole. We will create examples for each scenario using the given ratios.## Step 2: Example for Ratio ### For the ratio , consider a scenario involving apples and oranges in a fruit basket.- **Part-to-Part**: If there is 1 apple for every 4 oranges, the ratio of apples to oranges is .- **Part-to-Whole**: The total number of fruits is . Thus, the ratio of apples to the total number of fruits is , and the ratio of oranges to the total number of fruits is .## Step 3: Example for Ratio ### For the ratio , consider a scenario involving students in a school.- **Part-to-Part**: If there are 75 boys for every 600 girls, the ratio of boys to girls is .- **Part-to-Whole**: The total number of students is . Thus, the ratio of boys to the total number of students is , and the ratio of girls to the total number of students is .
