Nico has a jar of candy containing strawberry butterscotch and root beer flavors. If there are 10 strawberry, 13 butterscotch and seven root beer candles, which ratio shows the quantity of the strawberry flavored candy to the total number of candies Nico owns.

To find the ratio, we need to add up the total number of candies Nico owns. Adding up the number of each flavor gives us: 10 + 13 + 7 = <<10+13+7=30>>30 total candies.

The quantity of the strawberry flavored candy to the total number of candies Nico owns can be written as a ratio of 10 to 30. Simplifying this ratio gives us 1:3 as the final answer.
