What is the ratio of heart stickers to star stickers?

To find the ratio of heart stickers to star stickers, we compare the two quantities. Judy has 12 heart stickers and 28 star stickers.

The ratio can be simplified as follows:

1. Write the ratio: 12 (heart stickers) to 28 (star stickers), which is 12:28.
2. Simplify the ratio by finding the greatest common divisor (GCD) of 12 and 28, which is 4.
3. Divide both numbers by the GCD:

– 12 ÷ 4 = 3

– 28 ÷ 4 = 7

So, the simplified ratio is 3:7.

The correct answer is A 3:7.
