ddd [48]

Solution:

<u>Note that:</u>

  • Abby's dog: 1.5 cups of food
  • Braxton's dog: 4.5 cups of food

Looking at the information we got, we can say that Braxton's dog eats more. Let's put them into ratio form (Braxton's dog:Abby's dog)

  • => (Braxton's dog:Abby's dog) = 4.5:1.5

<u>Now, put them into fractions.</u>

  • => 4.5:1.5 = 4.5/1.5 = 3

We can conclude that Braxton's dog eats 3 times more food.
