Question

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. How many kilocalories are there in this 2-cup serving?

Answer 1

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;

$\frac{1600}{5} =\frac{x}{2}$

Multiply both sides by 2 we get;

$x = \frac{1600}{5} \times 2$

Simplify:

$x = 320 \times 2 = 640 kilocalories$

Therefore, 640 kilocalories are there in this 2-cup serving.
