Question

There are 8 fluid ounces in one cup. If you amount of fluid ounces, will the amount of cups also double? Write an argument that can be used to defend your solution.

Answer 1

If you double the amount of fluid ounces, then the amount of cups will double as well. This is a true statement.

Consider the statement "there are 8 fluid ounces in one cup" to be written as the equation

8 fluid ounces = 1 cup

We can multiply both sides by 2 to get

16 fluid ounces = 2 cups

We must multiply both sides by the same number to keep the equation the same (keep things balanced).
