Martha opens a bag of skittles. The bag contains 8 red, 5 yellow, 6 green,4 purple, and 2 orange. What percent of the skittles i
Helga [31]

Answer:

24%

Step-by-step explanation:

First, you would need to add up the total amount of skittles in the bag.

8+5+6+4+2=25 skittles in total.

We already know that 6 of these skittles are green. Therefore, we could say that 6 out of 25 skittles are green (or as a fraction, 6/25).

6/25 skittles are green. You can now easily convert this fraction into a decimal by doing 6 divided by 25 (6/25 = 0.24)

To convert this decimal into a percentage, simply multiply by 100.

0.24 x 100 = 24%
