Question

Sarah packed 12 boxes of sweets each weighing 625 grams. What is the total weight of sweets Sarah packed?

• A. $7kg$
• B. $7.5kg$
• C. $8kg$
• D. $8.5kg$

Answer 1

The correct option is B

$7.5kg$

Weight of one box of sweet $=625g$
Number of boxes $=12$
Total weight of the sweets = $625\times 12=7500g$

We know $1g=\frac{1}{1000}kg$
$\therefore 7500g=\frac{7500}{1000}kg$
$\Rightarrow 7500g=7.5kg$
