Question

A box contains $1000$ biscuits each weighing $5\text{grams}$. What is the weight of all the biscuits in the box in both $\text{grams (g)}$ and $\text{kilograms (kg)}$?

Answer 1

Number of biscuits in box $=1000$
Weight of one biscuit $=5\text{g}$
Weight of $1000$ biscuits
$=\text{(Weight of one biscuit)}\times$ $\text{(Number of biscuits in the box)}$
$=(1000\times 5)\text{g}$
$=5000\text{g}$
$\because$ $1\text{kg}=1000\text{g}$
$\therefore$ $\text{Weight in kg}$ $=\frac{5000}{1000}$$=5\text{kg}$
