Answer:

a) 15 000 litres

b) 1/3

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.
