Simon class donated [tex]7\frac{4}{5} \text{ or } 8[/tex] boxes of books
Given that,
On Monday Simon's class filled [tex]3\frac{2}{5}[/tex] boxes with books to donate
On Wednesday the class filled [tex]4\frac{2}{5}[/tex] more boxes with books
To find: total number of boxes of books donated
Total number of boxes of books donated = boxes filled in monday + boxes filled in wednesday
From given statement,
Boxes of books filled in monday = [tex]3\frac{2}{5} = \frac{5 \times 3 +2}{5} = \frac{17}{5}[/tex]
Boxes of books filled in wednesday = [tex]4\frac{2}{5} = \frac{5 \times 4+2}{5} = \frac{22}{5}[/tex]
Therefore,
Total number of boxes of books donated = [tex]\frac{17}{5} + \frac{22}{5}[/tex]
[tex]\rightarrow \frac{17}{5} + \frac{22}{5} = \frac{17+22}{5} = \frac{39}{5} = 7\frac{4}{5} = 7.8\\\\\rightarrow 7.8 \approx 8[/tex]
Thus simon class donated [tex]7\frac{4}{5} \text{ or } 8[/tex] boxes of books
