Question

# How many $250$ ml packets can be packed from a $10$ litre milk?

Hint: You can use the formula-
$\Rightarrow$ Number of packets=$\dfrac{{{\text{total quantity of milk}}}}{{{\text{capacity of one packet}}}}$
Put the given values and solve to get the answer.

Given, total quantity of milk=$10$ liters
Capacity of packets=$250$ml
We know that $1$ litre=$1000$ ml then
$\Rightarrow$ $1$ ml=$\dfrac{1}{{1000}}$ litres
Then $250$ml=$\dfrac{{250}}{{1000}}$ litres
We have to find the number of packets to pack the milk.
We can use the formula-
$\Rightarrow$ Number of packets=$\dfrac{{{\text{total quantity of milk}}}}{{{\text{capacity of one packet}}}}$
On putting the given values we get,
$\Rightarrow$ Number of packets=$\dfrac{{10 \times 1000}}{{250}}$
On simplifying we get,
$\Rightarrow$ Number of packets=$\dfrac{{10 \times 100}}{{25}}$
$\Rightarrow$ Number of packets=$\dfrac{{2 \times 100}}{5}$
On multiplying the numerator we get,
$\Rightarrow$ Number of packets=$\dfrac{{200}}{5}$
On dividing numerator by denominator, we get
$\Rightarrow$ Number of packets=$40$
$40$ packets of $250$ml can be packed from a $10$ litre milk.

Additional Information: Litre and milliliter are the standard units used to measure the capacity of liquid. Capacity is the maximum amount a container or vessel can hold in it. Litre is used to measure larger capacities like petrol, diesel, and oil while milliliter is used to measure smaller quantities like liquid medicines, water in a cup or bottle.

Note: We can also solve this question by this method-
Capacity of packets =$250$ml
And we have to pack $10$ litre milk.
We know that $1$ litre=$1000$ ml=$250 \times 4$ml
This means that to pack one litre milk, we need $4$ packets of $250$ml
Then to pack $10$ litre milk we need the number of packets=$4 \times 10 = 40$ packs of $250$ml
Hence we need $40$ packets of $250$ml to pack $10$ litre milk.
