### Example Question #12 : Numbers And Operations

Carlos owns a hamburger and hot-dog stand. When the fridge in the stand is full, there are 16 hamburgers and hot dogs total. If the ratio of hamburgers to hot dogs is always 5:3, how many hot dogs are in the cart when it is full?

**Possible Answers:**

**Correct answer:**

When solving a ratio problem, first add each part of the ratio:

So, one part in this ratio is equal to **8**. The number of hamburgers and hot dogs in the fridge is currently only the amount it can hold. To figure out how much it can hold total, we can multiply by the denominator of the fraction since the numerator is 1.

64 is the total amount of hamburgers and hot dogs that can be held in the fridge. Divide 8 into 64 in order to figure out how many parts fit into this number.

This number tells us how many times we need to multiply the ratio by in order to figure out how many hamburgers or hot dogs can be in the fridge at once. Since we are trying to figure out how many hot dogs are in the fridge when it is full, we use the second number, 3. We use the number **3** because, since the ratio is *hamburgers to hotdogs, *the second number represents the number of hot dogs.

This gives you your answer. There are **24 **hot dogs in the fridge when it is full.
