If 1/3 of a tank holds 80 litres of water, then the quantity of water that 1/2 tank holds is _____?
Answer: 120 litres
Explanation
If 1/3 of the tank holds 80 litres, we can set up a proportion to find the total capacity of the tank:
1/3 × Total Capacity = 80 litres
To find the total capacity, we can multiply both sides by 3:
Total Capacity = 80 litres × 3
= 240 litres
Now, we can find the quantity of water that 1/2 tank holds:
1/2 × Total Capacity = 1/2 × 240 litres
= 120 litres
