Question

Charles has a puppy that weighs 1.75 kilograms. The puppy weighed 1 kilogram when it was born. How much weight, in grams, has the puppy gained since it was born?

Answer 1

The puppy has gained 750 grams of weight since it was born

Answer 2

Hey You!

1.75 - 1 = .75

So the puppy grew .75 kilograms, but we need the weight in grams.

Convert:

1 kilogram = 1000 grams. This means the weight is less than 1000 grams.

.75 kilograms = 750 grams.

So, the puppy gained 750 grams of weight.
