Porshia · Answer

Steps: 
 
 You do 1/20 times 4 which equals 1/5 (when simplified) 
 You convert 1/5 to 2/10 which can be turned into .2 
 You do 12.2 minus .2 
 Your answer is 12 ounces

Porshia · Answer

After eating 4 buffalo burgers, Ken has 12.0 ounces of ketchup left in his 12.2-ounce bottle. He uses 0.2 ounces of ketchup for the burgers. The calculation involved using multiplication to find the total used and then subtracting it from the original amount.
