Brian works at an ice cream shop. For every 4 scoops of chocolate ice cream sold, 5 scoops of vanilla are sold and 2 scoops of strawberry are sold. Draw a picture to represent how many chocolate, strawberry, and vanilla scoops are sold when eight scoops of chocolate are sold. Express the ratio of vanilla scoops to strawberry scoops as a decimal when 12 vanilla scoops are sold? Does the ratio expressed as a decimal change when 8 scoops of vanilla are sold? Why or why not?
