Niko has a jar of candy containing strawberry, butterscotch, and root beer flavors. If there are 10 strawberry, 13 butterscotch, and 7 root beer candies, which ratio shows the quantity of the strawberry-flavored candy to the total number of candies Niko owns?

A. 13 : 30
B. 10 : 13
C. 10 : 30
D. 7 : 30

The total number of candies Niko owns is 10 + 13 + 7 = <<10+13+7=30>>30 candies.

The ratio of the strawberry-flavored candy to the total number of candies is 10 : 30.
Therefore, the answer is C. 10 : 30.

To find the ratio of strawberry-flavored candy to the total number of candies, we need to add up the quantities of all the candies and then compare that to the quantity of strawberry candies.

Total candies = 10 + 13 + 7 = 30

Strawberry to total = 10 : 30

Therefore, the correct ratio is C. 10 : 30

To determine the ratio of the strawberry-flavored candy to the total number of candies Niko owns, we need to find the quantity of strawberry-flavored candy and the total number of candies Niko has.

According to the information given, Niko has 10 strawberry-flavored candies, 13 butterscotch-flavored candies, and 7 root beer-flavored candies.

To find the total number of candies Niko owns, we sum up the quantities of each flavor: 10 + 13 + 7 = 30.

Now, we can express the ratio of the strawberry-flavored candy to the total number of candies as a fraction and simplify it if possible.

The quantity of the strawberry-flavored candy is 10, and the total number of candies is 30.

Therefore, the ratio of strawberry-flavored candy to the total number of candies is 10 : 30.

Simplifying the ratio by dividing both numbers by their greatest common divisor (which is 10 in this case), we get 1 : 3.

So, the answer is C. 10 : 30.
