Answer:
Step-by-step explanation:
Let the total capacity of the tank be x litres
As per statement tank is three-eighths full of water.
Tank is 3/8 full means the water in the tank is 3x/8 litres
Thus the water the tank can hold in empty space
x - 3x / 8
(8x-3x) / 8
5x/8
It would take another 45 litres of water to fill it. Means
5x/8 = 45
Cross multiplication
5x = 45 × 8
5x = 360
x = 360/5
x = 72
The tank can hold altogether 72 litres of water
Answer =the tank can hold altogether 72 litres of water
