Question

A box of vegetables weighs $18\frac{3}{5}$ pounds and a box of fruits weighs $10\frac{1}{5}$ pounds. Find the total weight of two boxes of vegetables and one box of fruits.

• A. $6\frac{1}{5}lb$
• B. $47\frac{2}{5}lb$
• C. $28\frac{4}{5}lb$

Answer 1

The correct option is B $47\frac{2}{5}lb$

Weight of 1 box of vegetables $=18\frac{3}{5}lb$

To find the weight of 2 such boxes, we will add $18\frac{3}{5}$ twice

Let's add $18\frac{3}{5}$ and $18\frac{3}{5}$

$18\frac{3}{5}+18\frac{3}{5}=18+\frac{3}{5}+18+\frac{3}{5}$

$=18+18+\frac{3}{5}+\frac{3}{5}$

$=36+\frac{6}{5}$

$=36+1+\frac{1}{5}$

Weight of 2 vegetable boxes $=37\frac{1}{5}lb$

Weight of fruit boxes:
Weight of 1 box of fruits $=10\frac{1}{5}lb$

Total weight = weight of 2 boxes of vegetables + weight of 1 box of fruits

Total weight $=37\frac{1}{5}+10\frac{1}{5}$

$=37+\frac{1}{5}+10+\frac{1}{5}$

$=37+10+\frac{1}{5}+\frac{1}{5}$

$=47+\frac{1+1}{5}$

$=47+\frac{2}{5}$

$=47\frac{2}{5}lb$

Thus, the total weight of two boxes of vegetables and one box of fruits will be $=47\frac{2}{5}lb$
