First you take the measurements you have, such as 1 pound equals 16 ounces and his bunny weighs 4 pounds. Then sense 1 pound equals 16 ounces you multiply 16 by 4 sense one pound is 16 ounces and his bunny weights 4 pounds. Then after multiplying you get your answer of 64 ounces.
To get ounces from pounds, use the variable x to stand for how many pounds you have. The formula would be: x pound Multiplied by 16=ounces. Replace your variable with 4 pounds and multiply it by 16 as in the formula, giving you the answer 64 ounces.
