There are 48 candies in a pack. Twelve are red. 18 are yellow. What is the ratio of reds to yellows?

Answer is   5:3

This means the ratio of reds to yellows is 5 to 3

Work Shown

We have 48 candies total and 18 yellow. This means there are 48-18 = 30 red assuming there are no other colors.

The ratio of red to yellow is 30:18. We simply list the number of reds (30), followed by a colon, then the number of yellows.

(number of red):(number of yellow)

The order is important. We cannot swap the items. This is because "reds to yellows" in the instructions has "red" come first.

Once you have the ratio 30:18, you divide both parts by the GCF 6 and you'll end up with the final answer 5:3

So for every 5 red candies we have 3 yellow candies. We can say "the ratio of reds to yellows is 5 to 3".
