Simon class donated 7\frac{4}{5} \text{ or } 8 boxes of books

<h3><u>Solution:</u></h3>

Given that,

On Monday Simon's class filled 3\frac{2}{5} boxes with books to donate

On Wednesday the class filled 4\frac{2}{5} 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 = 3\frac{2}{5} = \frac{5 \times 3 +2}{5} = \frac{17}{5}

Boxes of books filled in wednesday = 4\frac{2}{5} = \frac{5 \times 4+2}{5} = \frac{22}{5}

Therefore,

Total number of boxes of books donated = \frac{17}{5} + \frac{22}{5}

\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

Thus simon class donated 7\frac{4}{5} \text{ or } 8 boxes of books
