To find the ratio of cupcakes to brownies, we need to look at how many cupcakes Nick bought compared to how many brownies he bought.
Nick bought:
- 3 cupcakes
- 2 brownies
The ratio of cupcakes to brownies is 3:2.
Now let's check which of the given options is equivalent to the ratio 3:2.
- 2:1 - This simplifies to 2:1, which is not equivalent.
- 4:6 - This simplifies to 2:3, which is not equivalent.
- 13:12 - This does not simplify to anything close to 3:2, so it is not equivalent.
- 24:16 - This simplifies to 3:2 (since 24 ÷ 8 = 3 and 16 ÷ 8 = 2).
Therefore, the correct answer is 24:16.
