4.3: Veterinary Weights

A veterinarian uses weights in kilograms to figure out what dosages of medicines to prescribe for animals. For every 10 kilograms, there are 22 pounds.

Calculate each animal’s weight in kilograms. Explain or show your reasoning. If you get stuck, consider drawing a double number line or table.

Fido the Labrador weighs 88 pounds.

so, we know the weight for 20, but what we want to know is the weight for 30 pounds, that is 30/20=1.5 times more.

So we need to multiply the number by 1.5 : 9*1.5=9+4.5=13.5

so the dog's weight in kilograms is around 13.5 kgs.

Spot the Beagle weighs 33 pounds.

Bella the Chihuahua weighs 5 1/2 pounds.

A certain medication says it can only be given to animals over 25 kilograms. How much is this in pounds?
