Final answer:
Diana drank a total of 4 3/4 cups of liquids.
Step-by-step explanation:
Addition in math is a process of combining two or more numbers. Addends are the numbers being added, and the result or the final answer we get after the process is called the sum. It is one of the essential mathematical functions we use in our everyday activities.
Addition as the operation in which we combine two or more quantities to find the combined value of the quantity. We use the symbol plus (+) for performing addition operations. For example, adding 5 and 6 we write it as 4 + 5 and their sum is 9.
Commutative property of addition: Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4 . Associative property of addition: Changing the grouping of addends does not change the sum. For example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 ) .
Diana drank a total of 4 3/4 cups of liquids.
