Since we have 5 dogs to 3 cats, we can find a scale factor. Our new proportion is x:15. To solve for this, we need to divide 15 by 3 to get our scale factor to find x. 15/3 = 5, so our scale factor is 5. Multiply 5 dogs by 5 to get the new ratio. Our new ratio is 25:15, meaning that we have 25 dogs total. Your answer is 25 dogs. I hope this helps!
