Find the ratio.

32 litres to 0.50 litres.

64 = 32/(1/2)

To find the ratio between 32 litres and 0.50 litres, we divide the two quantities.

The ratio is calculated as follows:

Ratio = 32 litres / 0.50 litres

To divide by 0.50 litres, we can multiply both sides by its reciprocal, which is 1 / 0.50 = 2.

Ratio = (32 litres / 0.50 litres) x (2 / 2)
= (32 litres x 2) / (0.50 litres x 2)
= 64 litres / 1 litre
= 64

Therefore, the ratio of 32 litres to 0.50 litres is 64:1.
