Ms. Peters has 36 red, blue, and green markers. She has an equal number of each color of marker. She arranges the red markers in 2 equal groups. How many red markers are in each group?
There are three colors. Divide three into 36 to get 12. Meaning that there are 12 green, 12 blue, and 12 red. She split the red markers into 2 equal group. Take 12 and divide that by 2, giving you 6.
