Question

On Monday Simon's class filled 3 2/5 boxes with books to donate to charity. On Wednesday the class filled 4 2/5 more boxes with books. How many boxes of books will Simon's class donate in all?

Answer 1

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

Solution:

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
