Answer:
Explanation:
To express the quantities given in ratio language, we need to determine the ratio between the number of books read by each person.
Lauren: For every 10 books Jamar read, Lauren read 40 books. This can be expressed as a ratio of 40:10, which simplifies to 4:1.
Henry: For every 10 books Jamar read, Henry read 70 books. This can be expressed as a ratio of 70:10, which simplifies to 7:1.
Jamar: Since Jamar is the reference point for the ratios, the ratio for Jamar will always be 1:1.
So, the ratios for the number of books read in a year are:
Lauren: 4:1
Henry: 7:1
Jamar: 1:1
These ratios represent the relative quantities of books read by each person in a year, simplifying the comparison between their reading habits.
