Mr. Hill had 8 bottles of apple juice and 48 bottles of orange juice in the end. This bar model shows that if we start with 3:2 and want 1:6 we can rewrite 3:2 as 9:6 so the 6’s match. This means the 8 boxes on the left that total 64 each represent 8 bottles so that the original 3:2 was really 72:48. After he sells 64 of the 72, he has 8 left and still has 48 orange juice bottles which simplifies to 1:6.
If you add the first two equations, you get 2 stars = 22 (the circles will cancel out. So STAR = 11. Substituting 11 ito either equation 1 or 2, for star gives CIRCLE = 9.
Using CIRCLE = 9 in the last equation gives TRIANGLE = 14.
