Red 20

orange 20
yellow 17
green 13
purple 10

Of the Skittles Becky saved, she kept all of the green and 1/2 of the orange. What fraction of the yellow Skittles did she eat?

Total = 80

80 - 13 - (1/2)20 = ?

Looks to me like she ate them all, since she only kept green and orange.

To find out what fraction of the yellow Skittles Becky ate, we first need to determine how many yellow Skittles she saved and how many she ate.

We are given that there were 17 yellow Skittles.

Next, we need to determine how many yellow Skittles Becky saved. We know she kept all of the green ones and half of the orange ones, but we are not provided with the exact number of orange Skittles. To calculate the number of saved yellow Skittles, we need to find the total number of orange Skittles and then identify the number of saved ones.

Let's calculate the number of orange Skittles Becky had. We are given that there were 20 red Skittles, 20 orange Skittles, and the orange ones are split in half. This means there were 20/2 = 10 saved orange Skittles.

Now we can calculate the number of yellow Skittles Becky saved. We subtract the number of saved green and orange Skittles from the total number of yellow Skittles:
17 - 10 = 7.

Becky saved 7 yellow Skittles.

Finally, we can determine the fraction of yellow Skittles that she ate by dividing the number of yellow Skittles she ate by the total number of yellow Skittles.

The number of yellow Skittles she ate is:
17 (total yellow Skittles) - 7 (saved yellow Skittles) = 10.

Therefore, Becky ate 10 out of 17 yellow Skittles, which can be expressed as the fraction 10/17.
