Question

Together, Paul's two cats have the same mass as her dog, 11kg

The mass of one cat is 1500g greater than the mass of the other.

What are the masses of the two cats?

Answer 1

Two cats = 11kg = 11 000g

One cat is 1500g greater than the other, so we take away the difference first and then divide by 2 to get the weight of the lighter cat.

11 000 - 1500 = 9500

9500 ÷ 2 = 4750g

The lighter cat is 4750g

The heavier cat is 4750 + 1500 = 6250g

Answer: The cats are 4750g and 6250g.
