3 orange picks for every 2 green if there are 25 picks in all how many pics are orange

The ratio of orange picks to green picks is 3:2. 3+2=5, which will be our divisor. 25:5 = 5, so the amount of orange picks are (5*3) = 15, and there will be (5*2) = 10 green picks. There are 15 orange picks in total

15 orange correct me if wrong
