Answer:
640 kilocalories are there in this 2-cup serving.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
As per the given statement: There are 1600 kilocalories in 5 cups of dog food that mike gives his adult dog. Mike gives his puppy 2 cups of the same dog food.
Let x kilocalories are there in 2-cup serving.
then, by definition of proportion;
[tex]\frac{1600}{5} =\frac{x}{2}[/tex]
Multiply both sides by 2 we get;
[tex]x = \frac{1600}{5} \times 2[/tex]
Simplify:
[tex]x = 320 \times 2 = 640 kilocalories[/tex]
Therefore, 640 kilocalories are there in this 2-cup serving.
