Step-by-step explanation:
ratio of red apples to green apples is 7:2
red apples = 63
First, divide 63 with 7
63/7 = 9
Next, multiply the number gotten with the ratio number for green apples
9 x 2 = 18
18 green apples were sold

If you cross multiply 63 over X and 7 over two you get 7x=126. Divide 126 by 7 and X=18
