A dog is 3times as heavy as a cat . number 1: what is the ratio of the dog weight to the cat.show correct working

Let's assume the weight of the cat is represented by x.

Since the dog is 3 times as heavy as the cat, we can represent the weight of the dog as 3x.

The ratio of the dog's weight to the cat's weight can be written as:

3x : x

Simplifying this ratio by dividing both terms by x, we get:

3 : 1

So, the ratio of the dog's weight to the cat's weight is 3 : 1.
