(3) One liter of milk is filled in two bottles of equal size. A quarter of the milk in one bottle was used to make tea. How many liters of milk were used for tea? In milliliters?
Another type of problem: What is 1/5 of 2/3?
Answer (1)
Let's solve the two parts of the problem step by step.
Milk used to make tea :
One litre of milk is filled in two bottles of equal size. This means each bottle contains 2 1 litre of milk.
A quarter of the milk in one bottle is used to make tea. This can be calculated as:
4 1 × 2 1 = 8 1 litre
So, 8 1 litre of milk was used to make tea.
To convert this to millilitres, we know that 1 litre = 1000 millilitres. Therefore:
8 1 litre = 8 1 × 1000 = 125 millilitres
Therefore, 125 millilitres of milk were used for tea.
Finding 5 1 of 3 2 :
To find 5 1 of 3 2 , you multiply the two fractions:
5 1 × 3 2 = 15 2
The result is 15 2 .
In summary, 8 1 litre or 125 millilitres of milk was used for tea, and 5 1 of 3 2 equals 15 2 .
