6 Orange picks

Step-by-step explanation:

All I did was I used trial and error. Since I know that the number would be too big if I said there were 20 green, I tried 15 green. Sure enough, that was the correct answer. 5 times 3 is 15, so you would need to do 2 times 3. The answer is 6 orange picks.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
