A basket contains 14 red balls,23 yellow balls and 17 blue balls.How many balls you have to take out of the basket to have 2 of each colour?
Red: 14-2=12, yellow: 23-2=21, blue: 17-2=15. 12+21+15=48. I used minus 2 since you're leaving 2 of each in the basket then added the totals from each equation to find out how many you would take out altogether.
6? lol. Be more specific.
