The pictograph below shows how many books five students have each
read this month. Each represents a fixed number of books.
Student | Books Read |
---|---|
Xuan | |
Javya | |
Natasha | |
Sanan | |
Brandon |
Brandon read \(28\) books this
month. How many books does each represent in the pictograph?
How many books were read in total by these students this month?
Since Brandon has \(7\) , we can skip count by \(7\)s until we
get to \(28\). Doing this gives \(7\), \(14\), \(21\), \(28\). This means that each
represents \(4\) books read by a
student.
Alternatively, we could use a fair share strategy to determine how
many books each represents. We draw seven ovals, and add a tally to each oval one at a time until \(28\) tallies have been
distributed. Then we end up with \(4\) tallies in each oval, which means that each
represents \(4\) books.
Since each represents \(4\) books read, we know that Xuan read \(5 \times 4 = 20\)
books, Javya read \(3 \times 4 = 12\) books, Natasha read \(10 \times 4 = 40\) books, Sanan read \(4 \times 4 = 16\) books, and Brandon read \(7 \times 4 = 28\) books.
Thus, in total these students read \(20 + 12 + 40 + 16 + 28 = 116\) books.
