Tyler sold 12 tuna sandwiches, and 15 cheese sandwiches. What is the ratio of tuna sandwiches sold to the TOTAL number of sandwiches sold

A: 12:27
B: 27:12
C: 12:15
D: 15:12

The total number of sandwiches sold is 12 + 15 = <<12+15=27>>27 sandwiches.

The ratio of tuna sandwiches sold to the total number of sandwiches sold is 12:27, which is option A: 12:27. Answer: \boxed{\text{A}}.

To find the ratio of tuna sandwiches sold to the total number of sandwiches sold, we need to add the numbers of tuna and cheese sandwiches together.

The total number of sandwiches sold is 12 + 15 = 27.

Therefore, the ratio of tuna sandwiches sold to the total number of sandwiches sold is 12:27.

So the correct answer is A: 12:27.

To find the ratio of tuna sandwiches sold to the total number of sandwiches sold, we need to add the number of tuna sandwiches and the number of cheese sandwiches.

Given that Tyler sold 12 tuna sandwiches and 15 cheese sandwiches, the total number of sandwiches sold is 12 + 15 = 27.

Now we can express the ratio as the number of tuna sandwiches (12) to the total number of sandwiches (27).

Therefore, the correct ratio is 12:27.

So, the answer is A: 12:27.
