In table groups work on p. 6 - 7 A. A typical can of o. j. concentrate holds 12 fluid oz. The standard recipe is: How large of a pitcher will you need to hold the juice made from a typical can? (Show or explain your answer) Part-to-whole Ratio 1 : 4 Scale up 12 : 48 48 oz. pitcher Double check: 1 can concentrate = 12 oz. 3 cans water = 36 oz. Total = 48 oz.

B. A typical can of lemonade concentrate holds 12 fluid oz. The standard recipe is: How large of a pitcher will you need to hold the lemonade made from a typical can? (Show or explain your answer) Part-to-whole Ratio 1 : 5 ⅓ Scale up 12 : 64 oz. pitcher Double check: 1 can concentrate = 12 oz. 4⅓ cans water = 52 oz. Total = 64 oz.

Part-to-whole Ratio 1 : 5 ⅓ Scale up 12 : 64 oz.
