If a class choose these color

RED 2/16
Blue 5/16
Green 3/16
What fraction of the class chooses one of these three colors?
Am I correct if I said 5/16 of the class chooses one of these three colors?

No.

2/16 + 5/16 + 3/16 = 10/16 = 5/8

To find the fraction of the class that chooses one of the three colors, you need to add the fractions for each color:

2/16 (RED) + 5/16 (Blue) + 3/16 (Green).

Adding these fractions gives you a total of 10/16.

Simplifying this fraction, you get 5/8.

Therefore, the correct fraction is 5/8, not 5/16 as you mentioned.

To determine the fraction of the class that chooses one of the three colors, we need to add up the fractions for each color.

From the given information, we have:

RED: 2/16
Blue: 5/16
Green: 3/16

To find the fraction of the class that chooses one of these three colors, we simply add up these fractions:

2/16 + 5/16 + 3/16 = 10/16

So, the fraction of the class that chooses one of these three colors is 10/16.

Therefore, you are correct in saying that 10/16 of the class chooses one of these three colors.
