Question

Jack recieves a package from his uncle's farm. The package contains $12$ watermelons, each weighing $1$ kg $500$ g. What is the total mass of the package in kg?

• A. $18$
• B. $12$
• C. $6$

Answer 1

The correct option is A $18$

Number of watermelons $=12$
Mass of one watermelon
$=1$ kg $500$ g
Total mass of the package
$=1$ kg $500$ g $\times 12$
$=12$ kg $6,000$ g

Note:
$1\text{kg}=1,000\text{g}1\text{g}=\frac{1}{1,000}\text{kg}$

$6,000\text{g}=\frac{6,000}{1,000}\text{kg}=6\text{kg}$

$\Rightarrow$ Total mass of the package
$=(12+6)\text{kg}$
$=18$ kg
