A swimming pool is filled at a constant rate.When half full the pool has had 7500 litres poured into it. a)How much will the pool hold when full?b) what fraction has been filled when 5000 litres of water are in the pool?

Respuesta :

Answer:

a) 15 000 litres

b) 1/3

Step-by-step explanation:

a) Since the pool has 7500 litres when half full, it must have double that when full.

7500 * 2 = 15 000

b) Since the full pool is 15000, when the pool has 5000 litres it has 5000 out of 15000, hence the fraction 5000/15000 which simplifies to 1/3.

Simplification: divide the numerator and denominator by 5000.

Answer:

a) 15000

b) 1/3
